An experiment requires 74.2 mL of ethyl alcohol. If the density of ethyl alcohol is 0.790 g/cm3, what is the mass of 74.2 mL of ethyl alcohol?
Density = mass / volume
Given density = 0.790 (g/cm^3)
Volume = 74.2 ml = 74.2 cm^3 ( 1 ml = 1 cm^3)
Therefore mass = density * volume
Mass = 0.790 (g/cm^3) * 74.2 (cm^3 ) = 58.618 g
