Propane `(C_(3)H_(8))` is used for heating water for domestic supply. Assume that for 150 kg of how water supply per day water must be heated from `10^(@)C` to `65^(@)C`. What moles and volume of propane in litres at S.T.P would have to be used for heating this amount of water?
[`DeltaH` (combustion) `C_(3)H_(8)` = -2050 kJ and specific heat of water = `4.184 xx 10^(-3)(kJ)/(g)`].
