What is the molarity of the final solution of 2.00mL of the 5.00M stock solution is diluted to 10.00mL to make solution A. Solution A undergoes a second dilution by taking 3.00mL solution A and diluting it to 25mL?

Question

I'm so confused by this. Please help.

Answer 1

Use mL1 x M1 = mL2 x M2 and it will work out OR, logic. Logic goes this way.
5.00M x (2.00/10.00) x (3.00/25.00) = ?
