Question

A chemistry student needs 50.0 mL of chloroform for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of chloroform is 1.48 g.cm . Calculate the mass of chloroform the student should weigh out. Round your answer to 3 significant digits. x 6 ?

Answer 1

Answer:

The chemistry student will need to weigh 74.0g of chloroform.

Explanation:

Density relates mass and volume and 1 cm⁻³ = 1 mL:

1.48 g of chloroform ____ 1 cm⁻³ chloroform

            m                  ____  50.0 cm ⁻³ chloroform

m = 74.0 g of chloroform.

Therefore, the chemistry student will need to weigh 74.0g of chloroform.
