How many molecules of HCl would react with 2 moles of Al?

2Al + 6HCl → 2AlCl3 + 3H2

3.612 × 10^24 molecules

Explanation:

The balanced chemical equation in this question is given as;

2Al + 6HCl → 2AlCl3 + 3H2

Based on the equation, 2 moles of Aluminum (Al) is needed to react with 6 moles of HCl

Since 1 mole of a substance is equal to 6.02 × 10^23 molecules;

This means that, according to the question, 6 moles of HCl needed to react with 2 moles of Al will contain;

6 × 6.02 × 10^23 molecules

= 36.12 × 10^23

= 3.612 × 10^24 molecules

In a nutshell, 3.612 × 10^24 molecules of HCl would react with 2 moles of Al.
