Solution

The correct option is A
13.75

The explanation for the correct option:
Option A is correct
The molar mass of CO₂ is 12 + 2(16) = 44g
We know that the 1 mole of any gas at S.T.P. occupies 22.4 l.
Then, a Mass of 7 liters of CO₂ is 44 ÷ 22.4 = 13.75,
The explanation for the incorrect option:
Option B is incorrect
Because after calculating we get the answer which is 13.75.
Option C is incorrect
Because after calculating we get the answer which is 13.75.
Option D is incorrect
Because after calculating we get the answer which is 13.75.
