Question

How many mL would it take to prepare 500mL of a 0.10M Nitric Acid (HNO3) solution from a stock solution that is 69.0% pure and has a specific gravity of 1.42g/mL?

Answer 2

Steps:
1. Convert Specific gravity to moles/L using molar mass of HNO3
2. Express the concentration of the stock solution in Moles/L
3. Express everything in L
4. Use V1M1 = V2M2
You have V1=0.5L and M1 = 0.1M. Calculate M2 from above and solve for V2
