Question

Ethanol has a density of 0.789 g/mL. What is the volume of 54.0 g of ethanol? V = M/D



42.6 mL

.146 mL

68.4 mL

72.3 mL

Answer 1

Answer:

The answer is 68.4 mL

Explanation:

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

$volume = \frac{mass}{density}$

From the question

mass = 54 g

density = 0.789 g/mL

So we have

$volume = \frac{54}{0.789} \\ = 68.4410646...$

We have the final answer as

68.4 mL

Hope this helps you
