WebThese estimates are corroborated by the vapor sampling Sagebiel (1997), who measured fuel-air mass ratios between .048 and .054 (mole fractions between 0.010 and 0.012) at 14kft. These values should be compared with a lean limit fuel-air mass ratio of 0.030 (mole fraction of 0.007) and a stoichiometric fuel-air mass ratio of 0.070 (mole fraction of 0.015). WebNotice that the mole fraction has no units on it and is written as a decimal value. Do not change it to percent. Note of caution: you could see the term "mole percent." It is simply the mole fraction mltiplied by 100. For example, in the problem just below, the mole fraction of cinnamic acid is 0.2885. Its mole percent would be 28.85%. citibank spanish river
