What is the mass of 87.94 mL of ethanol, which has a density of 0.79 g/mL?

The answer is

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

volume of ethanol = 87.94 mL

density = 0.79 g/mL

The mass of ethanol is

mass = 87.94 × 0.79

mass = 69.4726

We have the final answer as
