Question

14 g of lithium reaction with ____ g sulfur to produce 46 of lithium sulfide.

Answer 1

32 g

Explanation:

We are given that

Mass of lithium=14 g

Mass of lithium sulfide=46 g

The reaction between lithium and sulfur is given below:

`2Li^++S^(-2)\rightarrow Li_2S`

14 g 46 g

According to law of mass conservation:

Mass of reactants=Mass of products

Mass of lithium+mass of sulfur=Mass of lithium sulfide

14g+mass of sulfur=46g

Mass of sulfur=46-14=32 g

Hence, mass of sulfur=32 g
