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.
