If a solution of sodium hydroxide is mixed from a 3M solution of sodium hydroxide, such that the volume of the original solution is 50ml and the volume of the final solution is 150ml, determine each of the following:
a. The volume of water added to the solution
b. The new concentration.
c. The mass of NaOH in both solutions.

  • Chemistry -

    you diluted it 3 times, so new concentration= .75M (you added one part orig, 2 parts water).

    volume added: 100ml
    Mass NaOH is the same in each.

    .05*3 moles x 40g/mole

    You have an easy teacher.
