Question

A sample of conc. nitric acid has a density of 1.41g/ml and contains 70% HNO3 by mass.
What mass of HNO3 is present per L of solution?
What is the molarity?

Answer 1

Assume 1 liter. then mass of acid is .7*1.41*1000, and from that calculate moles acid
Volume is 1liter,

molarity=molesacid/1

Answer 2

s12

Answer 3

.987 g HNO3

M=.0157
