**DrBob222**, Sunday, May 5, 2013 at 12:00pmWhat'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

**DrBob222**, Sunday, May 5, 2013 at 10:31pmJohn, 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.
