O CHEMICAL REACTIONSPercent yield of chemical reactionsGaseous butane (CH;(CH2),CH3)reacts with gaseous oxygen gas (0,) to produce gaseous carbon dioxide (CO,) and gaseous water (H,O). If 35.1 g ofcarbon dioxide is produced from the reaction of 37.2 g of butane and 86.5 g of oxygen gas, calculate the percent yield of carbon dioxide.Round your answer to 3 significant figures.

Data given: Mass of carbon dioxide = 35.1 g Mass of butane = 37.2 g Mass of oxygen = 86.5 g The balanced chemical reaction for the reaction of gaseous butane (CH3(CH2)2CH3) with gaseous oxygen (O2) is 2 CH3(CH2)2CH3 (g) +13 O2 (g) → 8 CO2 + 10 H2O Molar mass of gaseous butane = 58.12 g/mol Molar mass of gaseous oxygen = 15.999 g/mol Number of moles of gaseous butane = mass of gaseous butaneMolar mass of gaseous butane= 37.2 g58.12 g/mol= 0.640 mol Number of moles of gaseous oxygen = mass of gaseous oxygenMolar mass of gaseous oxygen = 86.5 g15.999 g/mol= 5.41 mol From the balanced chemical reaction, 2 mol gaseous butane produces 8 mol CO2 0.640 mol gaseous butane produces ? mol CO2 Number of moles of CO2 produced = 0.640 mol×8 mol2 mol=2.56 mol From the balanced chemical reaction, 13 mol gaseous oxygen produces 8 mol CO2 5.41 mol gaseous oxygen produces ? mol CO2 Number of moles of O2 produced = 5.41 mol×8 mol13 mol=3.33 mol Number of moles of CO2 produced is less in the case of gaseous butane. So gaseous butane is the limiting reagent. Mass of 1 mol CO2 is equal to 44.01 g Mass of 2.56 mol CO2 is equal to ? g Mass of CO2 = 2.56 mol×44.01 g1 mol=112.67 g Percentage yield = actual yieldtheoretical yield×100% Percentage yield of CO2 = 35.1 g112.67 g×100=31.1% The percent yield of carbon dioxide = 31.1%
