Na3N decomposes to form sodium and nitrogen gas at STP. If 13.7 L of nitrogen is produced how many moles of Na3N was used? (22.4 L = 1 mole of any gas)
2Na3N --> 6Na + N2

1.224 moles of were used.

Explanation:

We are given:

Volume of nitrogen gas produced = 13.7 L

At STP conditions:

22.4 L of volume is occupied by 1 mole of a gas

Applying unitary method:

13.7 L of nitrogen gas will be occupied by =

For the given chemical reaction:

By Stoichiometry of the reaction:

1 mole of nitrogen gas is produced by 2 mole of

So, 0.612 moles of nitrogen gas will be produced from = of

Hence, 1.224 moles of were used.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
