A molecular compounds dissolves in water to give up H+ ions and SO4^2- ions. If the compounds dissolved was HSO4^-, what mass of SO4^2- exists in the solution if 10 moles of it were dissolved?

a) 96.07 g
b) 130.22 g
c) 192.14 g

The answer I came up with is (a), but what about the 10 moles. (a) is the mass of the compound. Please show me what I'm not doing right or not seeing.

Hi there,

Thing to realize here is that 1 mole of HSO4^- goes to 1 mole of H+ and 1 mole of SO4^2-


10 moles of HSO4^- goes to 10 moles ...
