Question

A chemistry student needs of carbon tetrachloride for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of carbon tetrachloride is . Calculate the volume of carbon tetrachloride the student should pour out. Be sure your answer has the correct number of significant digits.

Answer 1

Answer:

34.6 cm³

Explanation:

A chemistry student needs 55.0 g of carbon tetrachloride for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of carbon tetrachloride is 1.59 g/cm³. Calculate the volume of carbon tetrachloride the student should pour out. Be sure your answer has the correct number of significant digits.

Step 1: Given data

• Mass of carbon tetrachloride (m): 55.0 g

• Density of carbon tetrachloride (ρ): 1.59 g/cm³

Step 2: Calculate the required volume of carbon tetrachloride

Density is an intrinsic property of matter. It can be calculated as the quotient between the mass of the sample and its volume.

ρ = m/V

V = m/ρ

V = 55.0 g/(1.59 g/cm³)

V = 34.6 cm³

The chemistry student should pour 34.6 cm³ of carbon tetrachloride.
