If you were to dissolve 14.00 grams of salicylic acid in enough water to make 400.00 mL of solution, what is the molarity of the final solution?
i did M = moles/L
so .1014 mol/.4000L = .2535 M
is this correct??
The next part of the question is
Now you take 50.00 mL of this solution and dilute it to 250.00 mL. What is the molarity.
I need help with this part. thankss

I get 0.2534 M. The difference is that you rounded the 14.00/138.12 to 0.1014 whereas I left the number (0.10136) in the calculator before dividing by the 0.4000.

what about the other part?

Just use M1V1 = M2V2
