Asked by Brenda

How do I solve what is the mass of a 32.5 mL sample of ethanol if the density of ethanol is .789 g/mL. I know Mass = Density * Volume. So 32.5 mL * .789g/mL = the mass, but I don't know how to solve that.
Answered by Steve
what, you can't multiply 32.5 * .789?

The units (mL) cancel, leaving just g, which is mass.

Density of ethanol=0.789g/ml
Volume of ethanol=32.5ml
Mass =?
Formular: Density=Mass/Volume
Therefore Mass=Density x Volume
=0.789 x 32.5
=25.64g
