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

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.
