Question

A chemistry student needs 65.0g of diethylamine for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of diethylamine is ·0.706gcm−3. Calculate the volume of diethylamine the student should pour out.

Answer 1

Answer: The student should pour out 92.068 cm³ of diethylamine.

Step-by-step explanation:

The equation for density is:
`d=m÷v`

We are given the density and mass of a liquid and asked to calculate the

volume of the liquid. We rearrange the equation to give

`v= m÷d`

v= 65.0 g÷0.706 g.cm³ = 92.068 cm³

The grams cancel, thus the unit left is cm³.
