    Answer:

    M1 = 6.0M

    V1 = 8.33mL

    M2 = 1.0M

    V2 = 50.0mL

    Explanation:

    It is possible to find the volume that we need to prepare a diluted solution from a stock using the equation:

    M1V1 = M2V2

    Where M is molar concentration and V volume of 1, stock solution and 2, diluted solution.

    Replacing:

    M1 = 6.0M

    V1 = Our incognite

    M2 = 1.0M

    V2 = 50.0mL

    6.0M*V1 = 1.0M*50.0mL

    V1 = 1.0M * 50.0mL / 6.0M

    V1 = 8.33mL of the stock solution are needed
