Question

Calculate molarity of HNO3 please help?
Calculate molarity of HNO3 prepared by dissolving 22.3 grams of HNO3 in water to make 875 ml of solution... Please help I'm stuck
Molarity of HNO3=moles/volume (L)

1 mole of HNO3=63.01 g
and
875mL=0.875L

Solve for moles:

22.3g*(1 mole/63.01g)=moles of HNO3

Molarity of HNO3=moles of HNO3/0.875L

***Answer contains no more then 3-significant figures.
0.405 mol/litres
