Review I Constants Periodic T
Butane, C4H10, reacts with oxygen, O2, to form
water, H2O, and carbon dioxide, CO2, as shown in
the following chemical equation:
CUipouu s.
2. Convert from moles of compound X to moles of compound Y using the coefficients in
the balanced chemical equation.
3. Convert from moles of compound Y to grams of compound Y using the molar mass of
compound Y.
2C4H10(g)1302(g)10H2O(g) +8CO2 (g)
The coefficients in this equation represent mole
ratios. Notice that the coefficient for water (10) is five
times that of butane (2). Thus, the number of moles
of water produced is five times the number of moles
Part B
of butane that react.
Calculate the mass of water produced when 6.96 g of butane reacts with excess oxygen.
Also, notice that the coefficient for butane (2) is one-
fourth the coefficient of carbon dioxide (8). Thus, the
Express your answer to three significant figures and include the appropriate units.
number of moles of butane that react is one-fourth

the number of moles of carbon dioxide that you
produce.
But be careful! If you are given the mass of a
compound, you must first convert to moles before
applying these ratios.
