Question

The density of ethanol is 0.789 g/mL at 20°С. Find the mass of a sample of ethanol that has a volume 150.0 mL at this temperature.

Answer 1

The answer is

118.35 g

Step-by-step explanation:

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

mass = Density × volume

From the question

volume of ethanol = 150.0 mL

density = 0.789 g/mL

It's mass is

mass = 150 × 0.789

We have the final answer as

118.35 g
