Using 25.0cm3 of aqueous lithium hydroxide, concentration 2.48mol/dm3, 2.20g of hydrated lithium sulfate was obtained. Calculate the percentage yield, giving your answer to one decimal place.
2LiOH H2SO4 → Li2SO4 2H2O Li2SO4 H2O → Li2SO4.H2O
The number of moles of LiOH used = .......................
The number of moles of Li2SO4.H2O which could be formed = .......................
Mass of one mole of Li2SO4.H2O = 128 g
The maximum yield of Li2SO4.H2O = .......................
percentage yield = .......................% [4]​
