Dentists sometimes use laughing gas (dinitrogen nonoxide, N0(g)) as a mild anaesthetic to keep patients relaxed during dental procedures. A cylinder uf laughing gas has a diameter of 23.0 cm and a height of 140 cmm. The pressure is 108 kPa and the temperalur is 294 K. How many grams of laughing gas are in the cylinder? What is the volume occupied by a 1.25g sample of helium al STP? What is the density of helium at STP?
