3. The thermochemical equation for the combustion of propane gas is as follows: C3H8(g) + 502(g) â 3CO2(g) + 4H20(g); Î110-2046 kJ/mol C3H8 (a) How much heat is produced from the complete combustion of 1.00 g of propane (C3Hs)? (b) The specific heat of water is 4.184 J/g.°C. How much energy (in k.J) is needed to heat 1.00 qt of water from 20.0°C to 100.0°C (1 .00 qt-946.4 g) (c) How many grams of propane gas (molar mass- 44.06 g/mol) must be combusted (burned) to provide enough energy required to heat 1.00 qt of water described in (b)? (Answer: (a) 46.4 kJ/g; (b) QH20-317 kJ; (c) 6.83 g)
