I have this problem....

Hexane has a density of 0.659 g/ml. How many milliliters (mL) would a student need to pour in order to get 49.5 g of hexane?

Am I to solve by using mass = density x volume? And if so, is the answer 32.62mL?

• Chemistry -

yes and no.
mass = volume x density
45.9g = volume x 0.695
Solve for volume. That answer is not 32.62 mL but more than twice that.

Okay, I think I got it! Thanks a bunch :)
