100ml of h2s04 solution having molarity 1M and density 1.5g/ml is mixed with 400ml of water. Calculate final molarity of h2s04 solution if final density is 1.25g/ml

50ml of 20.8% bacl2 and 100ml of 9.8% h2s04 solutions are mixed. Molarity of cl ions in the resulting solution is At. Wt of Ba = 137

Thank all tutors for your help me again

• chemistry -

I answered both question earlier. You have a lot of information that is not needed. Changing 980 % to 9.80% makes it make more sense but that number isn't needed either.
