A student needed to make 200 ml of 0.1 M naOH. If the stock soluton was 0.75 M, how much of the stock solution and how much wter would be needed to make this solution?

  • chemistry -

    mL1 x M1 = mL2 x M2
    200 x 0.1 = mL2 x 0.75 so you need 26.7 mL of the stock solution and enough water to make 200 mL of solution. Watch the number of significant figures.
