8. • Gases are usually expressed in terms of volumes.
• In case the volume of the gas is measured at room temperature and
pressure (or any condition other than NTP), convert it into NTP by
applying gas laws.
• Volume of a gas at any temperature and pressure can be converted
into its weight and vice-versa with the help of the relation,

completely burnt in oxygen to form SO2
• What is the volume (in L) of oxygen consumed
at STP?
