Quizplus · Accepted Answer

We know that at STP conditions, 1 mole of any gas occupies a volume of 22.4 L.
The molar mass of 11ea71d0_de47_91ce_91e5_51c502172493_TB6077_11 is 371 g/mol.
So, the number of moles of 11ea71d0_de47_91ce_91e5_51c502172493_TB6077_11 present in 11 g = (11/371) moles.
Therefore, the volume of 11 g of 11ea71d0_de47_91ce_91e5_51c502172493_TB6077_11 at STP conditions = (11/371) x 22.4 L = 0.67 L ≈ 3.8 L.
Hence, Option B is the correct answer.

At STP Conditions,11 G of Have a Volume of ________
