For solution A the concentration is 7.00x10^-4 mol/L. You transfer 10ml of the solution A out into a 10 dram vial and add 10mL of 0.1M HCL acid solution, and the new mixture is called solution B. What is the concentration of solution B?
The Attempt at a Solution
is this right approach? first find the mol of solution A, and then find the mol of HCl. Add them together and divided by the total volume.
