KNO3+H2SO4=K2SO4+HNO

Question

what mass of sulfuric acid in gram is needed for 2 moles of potassium nitrate?

how many moles of mitric acid will be produced from 5 moles of sulfuric acid?

what mass in gram of potassium sulfate will be produced from 5 moles of potassium sulfate?

Answer 1

The corrected equation is as follows and I've balanced it as well:
2KNO3 + H2SO4 = K2SO4 + 2HNO3

mols H2SO4 needed = 2 mols KNO3 x (1 mol H2SO4/2 mol KNO3) = 2*1/2 = 1 mol H2SO4 needed.
g H2SO4 = mols H2SO4 x molar mass H2SO4.

b.
5 mols H2SO4 x (2 mol HNO3/1 mol H2SO4 = 5 x 2 = ?

c.
I don't think you posted the right question for c. I suspect you exchanged some things. I think you probably wanted to know grams K2SO4 produced by 5 mol KNO3.

That's 5 mol KNO3 x (1 mol K2SO4/2 mol KNO3) = ?
Then grams = mols x molar mass.
