ok, so i have to find the mass of the HNO3 in 1 L and the mass of the H2O in 1 L. I'm given: HNO3 solution 1.42 g/mL 16M I'm really terrible at this stuff and it should be easy, but I have no idea where to start.

ok, sweet. i had most of that set up right. so the mass of HNO3 = 1008 g & the mass of H2O = 412 g?
