a 35.0ml sample of 37% hcl solution has a density of 1.18g/ml. the sample is diluted to a volume of 0.125L. what is the molarity of the final solution ?

    What's the molarity of the HCl?
    1.18 g/mL x 1000 mL x 037 x (1 mol/36.5g) = ? M

    Then mL1 x M1 = mL2 x M2

    John, I did everything but draw a picture and we can't draw pictures on this forum.
    The first part is 1.18 x 1000 x 0.37 x (1/36.5) = APPROXIMATELY 12 M but you do the math yourself and use your number.
    Then
    35.0 = mL1
    12 = M1
    125 = mL2
    M2 = unknown
    35.0 x 12 = 125 mL x M2
    Solve for M2 of the diluted solution.
    Your answer should be about 3.5M.
