Question

"Use a 10% w/v nitric acid solution."

How to prepare 10% w/v nitric acid solution?
Do I just weigh 10g of conc nitric acid (65%) and dilute to 100ml with water?

Answer 1

Use this formula
C1V1=C2V2
65(x)=10(100)
x=10(100)/65=15.38 ml of 65% nitric acid dilute to 100 ml to get 10% nitric acid

Answer 2

yes

Answer 3

That is correct! To prepare a 10% w/v nitric acid solution using a 65% nitric acid concentrate, you would measure out 15.38 mL of the concentrate and dilute with enough water to make a total volume of 100 mL.
