Answer:
9.4L
Step-by-step 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
