Please calculate volume of 70% Nitric acid required to prepare 200 liters of 5% HNO3 soultion.

C1 X V1 = C2 X V2 , Where
C1 = Concentration of HNO3 (70%)
V1 = Volume of HNO3 (70%) required
C2 = Conc. of HNO3 (5%)
V2 = Volume of HNO3 (200 Liter)

Therefore, V1 = (C2 X V2) / C1
V1 = (5 X 200) / 70
V1 = 1000 / 70
V1 = 100 / 7 = 14.28 liter
Therefore, 14.28 liter of 70% Nitric acid should be taken and diluted with sufficient water to get 200 liter of 5% Nitric acid solution.
