Sodium hydrogen carbonate, on heating, produces sodium carbonate, water and carbon dioxide. A recipe for chocolate chip cookies requires 1.5 dm' of carbon dioxide.
Calculate the mass of sodium hydrogen carbonate that should be used at R. T.P.
INa = 23; H = 1: C = 12; O = 16.]
[Note that 1 mole of gas occupies a volume of 24,000 cm at room temperature and pressure (RTP)]

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?
