Question

ethanol is a common laboratory solvent and has a density of 0.789 g/ml what is the mass in grams of 139 mL of ethanol

Answer 1

mass = volume * density

139ml * .789g/ml = 109.671 g

Answer 2

Ethanol is a common laboratory solvent and has a density of 0.789 g/mL. What is the mass, in grams, of 121 mL of ethanol?

Answer 3

D=m/V
0.789x 127=V
V=1.0023x10^2
