How many liters would 30g of Cl2 gas make?

9.4L

Explanation:

Given parameters:

Mass of Cl₂ gas  = 30g

Unknown:

Volume of gas  = ?

Solution:

To solve this problem, let us assume that this reaction takes place under standard temperature and pressure conditions.

Therefore;

             Volume of gas  = number of moles  x 22.4

To find the number of moles;

              Number of moles  =

                  molar mass of  Cl₂ = 2(35.5)  = 71g/mol

            Number of moles  =   = 0.42mole

So;

            Volume of gas = 0.42 x 22.4  = 9.4L
