Flowchart showing mass to moles to gas volume at RTP, with balanced equation coefficients linked to moles and gas volumes

At the same temperature and pressure, equal amounts in moles of gases occupy equal volumes. That is why gas questions can often be solved by thinking in moles first, then converting to volume.
