. Find the mass of KNO3 required to produce 126 kg of nitric acid


Find the mass of KNO3 required to produce 126 kg of nitric acid. Find whether a larger or smaller mass of NaNO3 is required for the same purpose.

KNO3+ H2SO4  → KHSO4 + HNO3

NaNO+ H2SO4  → NaHSO4 + HNO3

Best Answer

Molecular mass of KNO= 101 g

63 g of HNO3 is formed by = 101 g of KNO3

So, 126000 g of HNO3 is formed by = 126000×101/63 = 202 kg

Similarly,126 g of HNO3 is formed by 170 kg of NaNO3

So, smaller mass of NaNOis required.
