How many moles of each product are formed when 3.65 grams of H2SO4 react to with KOH?

2KOH + H2SO4 ==> K2SO4 + 2H2O

mols H2SO4 = grams/molar mass = 3.65/98 = estimated 0.04
You get 1 mol K2SO4 for every mole H2SO4; therefore 0.04 estd mols K2SO4.
You get 2 mols H2O for every mole H2SO4; therefore, 0.08 estd mols H2O.
You need to do the exact math.
