Question 135

In a different electrolysis, molten lithium chloride (

2LiCl→2Li+Cl2 2\text{LiCl} \rightarrow 2\text{Li} + \text{Cl}_2 2LiCl→2Li+Cl2​

) is decomposed.

(Relative atomic masses:

Li=7 \text{Li} = 7 Li=7

,

Cl=35.5 \text{Cl} = 35.5 Cl=35.5

; Relative formula mass of

LiCl=42.5 \text{LiCl} = 42.5 LiCl=42.5

)

Calculate the maximum mass of lithium that could be formed from 170 g of lithium chloride.
