2A + 3B--> A2B3 If 3mL of 0.04M A, 4mL of 0.02M B and 3mL of H2O was into a reaction test tube, what are the concentrations of A and B in the test tube.

Explanation:

Hello,

In this case, given the concentration and volume of each reactant, we first compute their moles in the solution:

Thus, since the total volume is computed given the volume of each reactant as well as the extra water, we have:

Thus, the concentrations of A and B are:

Best regards.
