Imagine you are working in a laboratory and you need to prepare a certain volume of gas at STP for an experiment. To calculate the volume of gas needed from the moles you have, which of the following formulas should be used?

• Volume = Moles × 22.4L

• Volume = Moles ÷ 22.4L

• Volume = Moles + 22.4L

• Volume = Moles - 22.4L

• 44.8 L

• 67.2 L

• 22.4 L

• 33.6 L
