How would you determine the concentration of H+, H2A and MB+ in a solution containing volumes of:

Question

H+ 600 microliters
H2A 500 microliters
MB+ 100 microliters
H20 800 microliters

Answer 1

Molar concentrations:

H+= .1M
H2A= .100M
MB+= 2.00X10^-4

Answer 2

I don't understand the problem.
