Homework Statement
Nitric acid is commercially available as a 72% ( w/ w) solution ( density, 1.42 g/cm3). How many milliliters of this reagent are needed to prepare 2.00 L of a 1.00M HNO3 solution?
Homework Equations
C%= (g HNO3/ g Solution) * 100
The Attempt at a Solution
So basically, I started with converting a mole of the solution to mL.
1 mol HNO3=44.37ml
But I feel like I need to first use the concentration to find how much reagent is in that 72%. so its .72g I assume that the reagent is contained in that solution.
so .72g of HNO3 in the solution is .507mL
but now I am stuck. How do I use that information to figure out what the mL of the reagent is needed to get 2L of 1 mol of HNO3
