Question

A chemistry student needs 30.0 of tetrahydrofuran for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of tetrahydrofuran is 0.889 g x cm^-3 . Calculate the volume of tetrahydrofuran the student should pour out.

Answer 1

Answer: The volume of tetrahydrofuran the student should pour out is 33.7 ml

Explanation:

Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{Volume}$

Given : Mass of tetrahydrofuran = 30.0 grams

Density of tetrahydrofuran = $0.889gcm^{-3}$

Putting in the values we get:

$0.889gcm^{-3}=\frac{30.0g}{Volume}$

$Volume=\frac{30.0g}{0.889gcm^{-3}}=33.7cm^3=33.7ml$      $(1cm^3=1ml)$

Thus volume of tetrahydrofuran the student should pour out is 33.7 ml
