Diluting acid with water

1. The problem statement, all variables and given/known data

To make 1000ml of 0.1M of Nitric acid with 65% Nitric acid.
Specific gravity= 1.42g/
Molecular weight= 63g/mol

2. Relevant equations
M = ((% x Specific gravity)/Molecular weight) x 10
cava = cfvf

3. The attempt at a solution

Re: Diluting acid with water

You presented a formula in your Relevant equations section. If you trust this formula then just substitute the values for the described information.

You could start with the number of moles of HNO3 you would want. If you know the moles of HNO3, then use formula weight to find number of grams of pure HNO3; but you know that your source is not pure, but instead is 65% w/w. so you have two more steps.... can you derive them?
