The concentration of commercially available concentrated nitric acid is 70.0 percent by mass, or 15.9 M. In 100 grams of solution, there are 1.11 mol of HNO3. Calculate the volume of 100g of the solution.

Hello

100 g solution = 1.11 moles HNO3
1000 g = 11.1 moles HNO3

and 1 L = 15.9 moles, so
1/15.9 L = 1 mole
11.1/15.9 L = 11.1 moles,

which together means, that 11.1/15.9 L are a mass of 1000 g
0.69811 L = 1000 g
1 L = 1000/0.69811 g = 1432.43 g --->
100 mL = 143.2 g
