Hello guys
I have 0.008 mol from substance A and 0.016 mol from substance B both dissolve in 40 ml of water. I need the concentration of each substance. Thanks in advance

c = n/V concentration = moles divided by volume

you mean like for substance A:
c=0.008/0.04 = 0.2 M , and for substance B:
c=0.016/0.04= 0.4 M ???

Correct

Thanks
