How much ml of H2So4 added to make 0.02M H2So4 solution to make volume 250ml?
You have to have the initial concentration of the sulfuric acid.
Here is an example: Pretend it is concentrated H2SO4 (12M).
you are diluting it 12/.02 or 60 times. So you need one part acid, 59 parts water.
1 part acid is 250/60, or 4.1ml acid
and the remainder is water. Always add acid to water.
