Question

How many liters would 30g of Cl2 gas make?

Answer 1

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 =
`(mass)/(molar mass)`

molar mass of Cl₂ = 2(35.5) = 71g/mol

Number of moles =
`(30)/(71)` = 0.42mole

So;

Volume of gas = 0.42 x 22.4 = 9.4L
