1A-8 Solve problems dealing with measurements of physical properties (mass, volume, density, temperature, heat, heat capacity, solubility)

1A-8-1. What is the density of a liquid if a 25.0 mL sample of the liquid has a mass of 20.00 g?
A. 0.8 g/mL, B. 0.800 g/mL,
C. 1.25 g/mL, D. 1.3 g/mL

1A-8-2. Glacial acetic acid is a liquid with a density of 1.06 g/mL. If an experiment calls for 5.0 g of acetic acid, what volume of glacial acetic acid do we need?
A. 4.7 mL, B. 4.72 mL, C. 0.21 mL, D. 0.212 mL

1A-8-3. Illustrated below is a commonly used procedure for determining the density of an irregularly shaped, water-insoluble solid. The solid is weighed, then submerged in water. Suppose the solid weighed 48.0 g and the water level in the cylinder rose from 20.9 mL to 26.9 mL The density of the solid is...
A. 2.0 g/mL, B. 2.00 g/mL,
C. 8.0 g/mL, D. 8.00 g/mL
