. 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
NaNO3 + H2SO4 → NaHSO4 + HNO3
Best Answer
Molecular mass of KNO3 = 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 NaNO3 is required.
