[10] The air-fuel ratios listed below are much higher than the equivalent oxygen-fuel ratios, due to the high proportion of inert gasses in the air. /CS Convert the number of moles of substance B to mass using its molar mass. Notice that the molar mass is placed with the grams at the bottom and mole at top. Even though 2 mol of H2 are needed to react with each mole of O2, the molar mass of H2 is so much smaller than that of O2 that only a relatively small mass of H2 is needed compared to the mass of O2. Finally, to calculate the amount of the other substances: You now know the number of moles of each substance needed in a theoretical perfect reaction. << << /Length 5 0 R /Filter /FlateDecode >> 100.
