Question

A 10.0 ml volume of alcohol has a mass of 7.05 g. what is the density of the alcohol in grams per ml?

Answer 1

Answer: The density of alcohol is 0.705 g/mL

Explanation:

To calculate density of a substance, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

We are given:

Mass of alcohol = 7.05 g

Volume of alcohol = 10 mL

Putting values in above equation, we get:

$\text{Density of alcohol}=\frac{7.05g}{10mL}=0.705g/mL$

Hence, the density of alcohol is 12.38 g/mL

Answer 2

Density is mass per unit volume. The units you specified are grams per ml.

So simply divide 7.05g by 10 ml.

=0.705g/ml.
