The equation for the complete combustion of one mole of an alkane can be represented by
alkane + ZO2 → XCO2 + YH2O
Complete combustion of one mole of the alkane produces 308 g of carbon dioxide and 144 g of water.
X, Y and Z are the numbers used to balance the equation.
Calculate the values of X, Y and Z.
[Mr of CO2 = 44, Mr of H2O = 18]
