Question

B. Density of Liquid

1. Obtain a sample of distilled water (any quantity of your choice) and
determine its mass and volume. Record your data on table 3 in the
experimental report

2. Calculate the density of the water sample using equation 1

Substance Density (g/mL) Substance Density (g/mL)
Aluminum 2.7 Lead 11.3
Brass 8.4 Zinc 7.1
Copper 8.9 Cork 0.26
Tin 7.3 Silver 10.5
Bone 1.80 Rhodium 12.4
Iron 7.9 Platinum 21.45

Density of Liquid

Density can be determined in the laboratory by measuring the mass and volume of
a substance. To measure the density of a liquid, first measure the mass of a clean,
dry beaker. Then add the liquid and find the combined mass of the beaker and
liquid. Subtract the mass of beaker from combined mass to determine the mass of
the liquid. Measure the volume of the liquid by placing it in a graduated cylinder and
using the proper technique to read its volume (Figure 1).

meniscus.
