Question

Ethanol is a common laboratory solvent and has a density of 0.789 g/mL. What is the mass, in grams, of 115 mL of ethanol

Answer 1

Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. Therefore, the mass can be calculated as:

mass = 0.789 ( 115) = 9.0735 g ethanol

Hope this answers the question. Have a nice day.
