The number of moles of A4B3 produced in a reaction is obtained by stoichiometry.
The term stoichiometry refers to mass-mole relationship. The first step in solving this problem is by writing the correct reaction equation as follows;
4A + 3B -------> A4B3
If 4 moles of A yields 1 mole of A4B3
10 moles of A yields 10 * 1/4 = 2.5 moles of A4B3
Therefore, 2.5 moles of A4B3 is produced.
