Question

To a reaction vessel, 21.5g of Li(s) and 21.3g of N2(g) are added. Given the reaction below, determine the maximum mass of Li3N that can be produced.

Li(s) + N2(g) --> Li3N

Answer 1

Li₃N ( Lithium nitride)

The law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products.

mass of reactants there = 21.5 g if Li + 21.3 g of Nitrogen

= 42.8 g

hence the mass maximum mass of Li3N produced is 42.8 g
