5) Determine the mass if lithium hydroxide that is produced when 12.87 g of lithium
netineya [11]

Answer: 26.54 grams

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of lithium nitride}=\frac{12.87g}{34.83g/mol}=0.369moles

Li_3N+3H_2O\rightarrow 3LiOH+NH_3  

Li_3N is the limiting reagent as it limits the formation of product and H_2O is the excess reagent

According to stoichiometry :

As 1 moles of Li_3N give = 3 moles of LiOH

Thus 0.369 moles of O_2 give =\frac{3}{1}\times 0.369=1.108moles  of LiOH

Mass of LiOH=moles\times {\text {Molar mass}}=1.108moles\times 23.95g/mol=26.54g

Thus  26.54 g of LiOH will be produced from the given mass.
