The equation of the ongoing reaction: H2SO4 + 2LiOH = Li2SO4 + 2H2O.
1) Find the amount of sulfuric acid substance. To do this, we first find the molar mass of the acid: 2 + 32 + 64 = 98.
Next, we divide the mass by the molar mass: 98/98 = 1 mol.
2) According to the reaction equation, one mole of sulfuric acid accounts for one mole of lithium sulfate. The amount of lithium sulfate substance is 1 mol.
3) Molar mass of lithium sulfate: 7 * 2 + 32 + 64 = 110.
4) Find the mass of lithium sulfate. For this, the amount of lithium sulfate substance is multiplied by the molar mass: 110 * 1 = 110g – the answer.
