what volume of a 5M H2 SO4 solution should be added to a 150 mL of 1.

1.	what volume of a 5M H2 SO4 solution should be added to a 150 mL of 1. M H2SO4 solution to obtain a solution of sulphuric acid of molarity 2.5?
Answer» ong>Answer: 5V+ 150= 375 + 2.5V So 2.5V=225 Therefore V=90. So adding 90 ml.of 5M H2SO4, to 150 ml.of 1M H2SO4 we get in the final mixture 250 ml.of 2.5M H2SO4. [NOTE: MULTIPLYING NO.OF ml OF SOLUTION WITH MOLARITY WILL GIVE NO.OF M.MOLES OF THE SUBSTANCE.]

ong>Answer:

5V+ 150= 375 + 2.5V

So 2.5V=225

Therefore V=90.

So adding 90 ml.of 5M H2SO4, to 150 ml.of 1M H2SO4 we get in the final mixture 250 ml.of 2.5M H2SO4.
