A 10 gram sample of natural gas containing CH_(4) and C_(2)H_(4) was burnt in excess of oxygen to give 29.0 "grams" of CO_(2) and some water. How many games of water are formed :

280 g of a mixture containing CH_(4) and C_(2)H_(6) in 5:2 molar ratio is burnt in presence of excess of oxygen. Calculate total moles of CO_(2) produced.

When 100 c.c. of a mixture of methane (CH_(4)) and ethylene (C_(2)H_(4)) was exploded with an excess of oxygen , the volume of carbon dioxide produced ( measured at the same temperature and pressure ) was 160 c.c. Calculate the heat evolved when 22.4 litre of the mixture of methane and ethylene ( measured at N.T.P. ) is completely oxidised to carbon dioxide and water at constant volume. CH_(4)+2O_(2)=CO_(2)+2H_(2)O+212000cal, C_(2)H_(4)+3O_(2)=2CO_(2)+2H_(2)O+333000 cal.
