Answer:

See attached image. The last problem was a challenge, but I can guarantee that it is the teacher's fault if I'm not correct.

Explanation:

On the attachment. Remember that all gasses occupy 22.4 liters at STP. It is a good constant to memorize. It often comes up in chemical calculations, and you can also use it at parties if you want to annoy anyone. Also, depend on the units to help you decide how to do a calculation. moles/liter or liters/mole: it makes a difference in whether you multiply or divide. Use the operation that cancels the units you don't want and leaves the target unit.
