(a) you are diluting the concentration by a factor of 6/.25=24
So, you will need 20/24 ml of 6M solution to produce 20ml of .25M solution. The rest, of course, is water.
Do the others in like wise.
What is the volume, in milliliters, required to prepare
a. 20.0 mL of a 0.250 M KNO3 solution using a 6.00 M KNO3 solution
b. 25.0 mL of a 2.50 M H2SO4 solution using a 12.0 M H2SO4 solution
c. 0.500 L of a 1.50 M NH4Cl solution using a 10.00 M NH4Cl solution
