Question

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

Answer 1

(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.

Answer 2

20.0 ml of a 0.250 solution M KNO soul using a 6.00 M KNO solution.Determine the volum, in milliliters, required to prepare each of the following.
