Answer:
0.0794 L
Explanation:
An experiment requires 62.7 g of ethyl alcohol. The density of ethyl alcohol is 0.790 g/mL. The volume, in milliliters, corresponding to 62.7 g of ethyl alcohol is:
62.7 g × (1 mL/0.790 g) = 79.4 mL
1 liter is equal to 1000 milliliters. The volume, in liters, corresponding to 79.4 mL is:
79.4 mL × (1 L/ 1000 mL) = 0.0794 L
