Question

Ethanol ia a common laboratory solvent and has a density of 0.789 g/mL. What is the mass, in grams, of 123 mL of ethanol?

Answer 1

Ok, let's star so the Density formula is this: d=m/V, to find the volume you're going to switch the place of V with d; V=m/D. And to find the mass it's m=d x V
So, m=.789 x 123 which is

97.047
