(a)
Interpretation: The figure which is closest to the correct answer needs to be determined.
Concept Introduction: Unit conversion is a process that involves division or multiplication using a numerical factor which results in the conversion of one unit to other. It also involves the selection of correct number of significant digits and rounding.
(a)
Explanation of Solution
For the length of the baseball bat following values are given:
100 mm, 100 cm and 100 m.
A normal baseball bat is of 42 inches. Converting this into cm as follows:
Converting 100 mm and 100 m to cm as follows:
Thus, 100 mm in cm will be:
Now converting 100 m to cm:
Here, 10 cm and 10000 cm are not correct values for length of a baseball bat thus, the value which is closest to the correct value for a length of baseball bat is 100 cm.
(b)
Interpretation: The figure which is closest to the correct answer needs to be determined.
Concept Introduction: Unit conversion is a process that involves division or multiplication using a numerical factor which results in the conversion of one unit to other. It also involves the selection of correct number of significant digits and rounding.
(b)
Explanation of Solution
For the volume of a glass following values are given:
23 cc, 230 mL and 23 L.
A normal glass can hold a volume of 240 mL.
The volume 23centimeter cubes is equal to 23 mL and 23 L is equal to 23000 mL which is not possible.
Thus, the closest value to the correct answer is 230 mL.
(c)
Interpretation: The figure which is closest to the correct answer needs to be determined.

(c)
Explanation of Solution
There are three figures given for the weight of a man:
75 mg, 75 g and 75 kg.
The average weight of a human body is 62 kg. This value is closer to 75 kg. The other figures are 75 mg and 75 g, the values in kg will be:
And,
Both the values are not possible for a weight of man thus, correct answer is 75 kg.
(d)
Interpretation: The figure which is closest to the correct answer needs to be determined.
Concept Introduction: Unit conversion is a process that involves division or multiplication using a numerical factor which results in the conversion of one unit to other. It also involves the selection of correct number of significant digits and rounding.
(d)
Explanation of Solution
The possible values for volume of tablespoon are given 15 mL, 150 mL and 1.5 L.
Here, 1.5 L can also be converted into mL as follows:
The normal capacity of a tablespoon is 15 mL thus, 150 mL and 1.5 L or 1500 mL are incorrect values.
The correct value is 15 mL.
(e)
Interpretation: The figure which is closest to the correct answer needs to be determined.
Concept Introduction: Unit conversion is a process that involves division or multiplication using a numerical factor which results in the conversion of one unit to other. It also involves the selection of correct number of significant digits and rounding.
(e)
Explanation of Solution
The figures for weight of paper clip are given 50 mg, 50 g and 50 kg.
The mass of a regular paper clip is around 1 g.
Converting 50 mg and 50 kg to grams.
And,
The value closer to 1 g is 0.05 g thus, 50 mg is correct answer.
(f)
Interpretation: The figure which is closest to the correct answer needs to be determined.
Concept Introduction: Unit conversion is a process that involves division or multiplication using a numerical factor which results in the conversion of one unit to other. It also involves the selection of correct number of significant digits and rounding.
(f)
Explanation of Solution
The figures for width of hand are given 100 mm 100 cm or 100 m.
The approximate width of hand is 3.5 inches.
Converting inches to mm as follows:
The value is closer to 100 mm. Thus, 100 mm is correct answer.
(g)
Interpretation: The figure which is closest to the correct answer needs to be determined.
Concept Introduction: Unit conversion is a process that involves division or multiplication using a numerical factor which results in the conversion of one unit to other. It also involves the selection of correct number of significant digits and rounding.
(g)
Explanation of Solution
The given figures for the weight of a flash drive are 8 mg, 8 g and 8 kg.
Mostly all flash drive weigh less than 30 g.
Here, 8 mg is 0.008 g and 8 kg is 8000 g.
Thus, the closest value to the correct answer is 8 g.

- A prescription of antibiotics for a 30lb child says to give 100mg three time daily. Is the dosage safe if the proper pediatric dosage range for this drug is 10-30mg per kilogram of body weight per day?arrow_forwardYou are a pharmacist at a drug store and a woman approaches you frantically, holding a bottle of Children's Advil. Her daughter has a fever and the company changed it's formulation. Now, she doesn't know how much medicine to give her daughter. With the old formulation, she gave 1.875 mL dosage that contained 50 mg of ibuprofen per 1.25 mL. The new formula contains 100 mg of ibuprofen per 5 mL. How many mL of medicine should the woman give her daughter?arrow_forwardAssume the recommended single dose of ibuprofen for children over the age of two is 4.5 mg per pound (mg/lb) 4.5 mg per pound (mg/lb) of body weight.

If a child weighs 75.9 lb and the available stock of Rocephin is 61 mg/ml, how many milliliters does the nurse administer to the child? Round your answer to the tenths place. 1 lb = 16 oz 1 kg = 2.20 lb 454 g = 1 lbarrow_forwardA mother calls you to ask about the proper dosage of cough medicine for her 2-year-old. The bottle says to administer 5.0mg/kg three times a day for children under 3 years of age. The cough syrup is supplied in a liquid that contains 50.0mg/mL. Part A How many teaspoons of cough syrup should she give the child, who weighs 24 lb, in each dose?arrow_forwardPure water has a density of 1.0 g/mL, and ethanol has a density of 0.789 g/mL. Assume a specific mouthwash is 12.8% ethanol by volume, and each bottle of the mouthwash contains a total volume of 1.25 pints. The density of mouthwash is 0.875 g/mL. Determine how many 1) ounces, 2) grams, and 3) pounds of ethanol there are in 53 bottles of this mouthwash. 1fl oz. = 28.35g. 1 liter = 2.11 pints. 1lb = 16 oz.arrow_forward
