Question 27
H

A student heats 5.40 g of aluminium with 14.2 g of chlorine.

2Al+3Cl2→2AlCl3\mathrm{2Al + 3Cl_{2} \rightarrow 2AlCl_{3}}2Al+3Cl2​→2AlCl3​

Relative atomic masses: Al=27\mathrm{Al} = 27Al=27, Cl=35.5\mathrm{Cl} = 35.5Cl=35.5.

What is the maximum mass of aluminium chloride that can form?
