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]

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
