Answer:
The answer is
69.47 g
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 = 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
69.47 g
