Answer:
329.7%
Explanation:
Percent Yield = Actual Yield/ Theoretical Yield x 100%
Percent Yield = 105.5g/32 x 100% = 329.69 ≈ 329.7 %
Li2CO3 + 2HNO3 ----> 2LiNO3 + H2O + CO2
Reaction equation:
Al(OH)₃ + 3HCl → AlCl₃ + 3H₂O
Moles of Al(OH)₃:
moles = mass/Mr
= 1.51 / (27 + 17 x 3)
= 0.019
Molar ratio Al(OH)₃ : HCl = 1 : 3
Moles of HCl required = 0.019 x 3
=0.057
concentration = moles/volume
volume = 0.057 / 0.1
= 0.57 dm³
= 570 ml
