I've got a balanced equation that is asking about and i have no idea where to start. i will attach the question below: 4a + 3b2 -> 2a2b3 if 12 moles of a are reacted with excess b2, how many moles of a2b3 will be produced?

6 mol of A₂B₃ are produced

Explanation:

This is the reaction:

4A  + 3B₂  →  2A₂B₃

4 moles of A react with 3 moles of B to produce 2 moles of A₂B₃.

Ratio is 4:2. Therefore:

4 moles of A will produce 2 moles of A₂B₃

12 moles of A, would produce (12 .2) / 4 = 6 moles
