What is the mass of 22.4 l of n2 at stp? 11.2 grams 14.00 grams 22.4 grams 28.01 grams

Option (d) is the correct answer.

Explanation:

It is known that every 1 mole of ideal gas contains volume of 22.4 liters. As the formula of nitrogen gas is .

Also in one mole, molecule contains two nitrogen atoms.

Hence, mass of 1 mole of nitrogen gas is 2 × molar mass of nitrogen.

Therefore, mass of 1 mole gas = 2 × 14

                                                                            = 28

Thus, we can conclude that mass of 22.4 L of at STP is 28.01 grams.
