how could you find the mass and volume from this info
Acetone (fingernail-polish remover) has a density of 0.7857 g/cm3.
oh i read the problem wrong. i guess i have to include this part
What is the mass in grams of 28.11 mL of acetone?
right. You can't have two unknowns without two equations.
mass = volume x density.
You have the volume and the density; you can calculate the mass.
