Concept Introduction:
The partial pressure of water vapor can be calculated using Dalton’s law of partial pressures.
According to Dalton’s law, the total pressure of the mixture of gases is equal to the sum of partial pressures of the individual gas.

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 of butane that react. Correct Part C Also, notice that the coefficient for butane (2) is one- fourth the coefficient of carbon dioxide (8). Thus, the 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. Calculate the mass of butane needed to produce 61.4 g of carbon dioxide. Express your answer to three significant figures and include the appropriate units. View…arrow_forward
