Liquid water has a density of 1.00g/mL at 10.0C and .996g/mL at 30.0C. Calculate the change in volume that occurs when 500mL of water is heated from 10.0C to 30.0C.

you have at 10 C 500 g. YOu have that same mass at 30, but volume=mass/denstiy
= 500/.996 ml= you do it. 
but i get 502.o and the answer in the back of my book said 2mL....so..
