Question

How many moles of chlorine are needed to react with 56.8g of Al
2Al+3Cl—> 2AlCl3

Answer 1

Answer:

3.15 moles of chlorine

Explanation:

first find out no. of moles of given aluminium using no.of moles= given mass / molar mass

then use unitary method

2 mole Al need 3 Mole Cl

than 1 mole Al require 3/2 mole of Cl

than 2.1 mole of Al require 3.15 mole of Cl
