Question 10

Aluminium reacts with chlorine according to the equation:

2Al+3Cl2→2AlCl32\text{Al} + 3\text{Cl}_2 \rightarrow 2\text{AlCl}_32Al+3Cl2​→2AlCl3​

A mixture contains 5.4 g of aluminium and 14.2 g of chlorine. The relative atomic masses (ArA_rAr​) are: Al=27\text{Al} = 27Al=27, Cl=35.5\text{Cl} = 35.5Cl=35.5.

Calculate the maximum mass of aluminium chloride that can be formed.
