Question

A chemistry student needs 55.0 g of tetrahydrofuran for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers thatthe density of tetrahydrofuran is 0.889 g.cm^-3. Calculate the volume of tetrahydrofuran the student should pour out.Be sure your answer has the correct number of significant digits.

Answer 1

The relationship between density, mass, and volume is given by:

`\text{volume}=\frac{\text{mass}}{\text{density}}`

Given parameters:

mass = 55.0g

density = 0.889 gcm^-3

The volume can be calculated as follow:

`volume=\frac{55g}{0.889\text{gcm}^(-3)_{^{^{^{}}}}}`

Hence, the volume is

`\text{volume}=61.9g`

Volume = 61.9 g (to 3 significant figure)
