How would you prepare 77 mL of a solution 0.02 M from a stock solution of 1.3 M ? (the volume of the water added is only an estimation. It would be correct if the density of the solution is equal to the density of the solvent, which is never the case, however the error in this case is quite small). V of the stock solution = ? V of water added ≈?
