Homework Answers
5) 68% w/ v means 68 gm of nitric acid is present in 100 mL
so volume of nitric acid in 2.12 gm = 100 mL x ( 2.12 gm / 68 gm ) = 3.12 mL
6) Molarity = mol / volume in litre
3.5 M = 0.02 mol / volume in litre
volume of sulfuric acid = 0.02 mol / 3.5 Mol Litre—1 = 5.714 x 10–3 litre = 5.7 mL
7 ) In 50 % V/ V solution means 100 ml solution has 50 mL nitric acid and 50 mL sulfuric acid.
volume of nitric acid = 3.12 mL
so volume of sulfuric acid = 3.12 mL
