Answer to Question #240802 in General Chemistry for San

Question

Combustion of hydrocarbon in a limited supply of air produces CO in addition to CO2 and h2o when 1.31 g of particular hydrocarbon was burned in air ,1.26 g CO ,1.98 g CO2

Answer 1

Molar mass of CO = 28.01

1.26 = 0.045m

Molar mass of CO₂= 44.01

1.98/44.01 = 0.045m

Molar mass of hydrocarbon = 28.06 mol

1.31/28.06 = 0.047m
