Your first step is to balance do you know how to do that?

2 LiOH + H2SO4 = Li2SO4 + 2 H2O

Yep that is balanced

So now we have to determine how may moles of H2SO4 are needed to react with the 8.4mols of LiOH So the first step to realize is that for every one mole of H2SO4 is used, two moles of LiOH are used. So: 8.4mol LiOH * (1 mol H2SO4/2mol LiOH) * (98.08g/mol H2SO4/1mol H2SO4)= ? g H2SO4

I got 4.2 moles

Ya it would be 4.2 mol of H2SO4
