According to the chemical equation

2C2H6(g) + 7O2(g) ---> 4CO2(s) + 6H2O(g)

a) how many mol of carbon dioxide will form by the complete combustion of 6.6 mol of C2H6?


According to the balanced chemical equation four mol of carbon dioxide are formed when two mol of ethane, C2H6, react. Carbon dioxide and ethane always combine in this ratio according to this equation. We can use this relationship as a unit conversion factor to convert between mol of ethane and mol of carbon dioxide.
