Calculate the final concentration of 50 ml of 0.25 mol. 1 NaCI made to a final volume of 250 ml.
The final concentration of NaCl is 0.1 mol/L.
50 mL x 0.25 mol/L = 12.5 mol
250 mL x 0.1 mol/L = 25 mol
12.5 mol/25 mol = 0.1 mol/L
50 mL x 0.25 mol/L = 12.5 mol
250 mL x 0.1 mol/L = 25 mol
12.5 mol/25 mol = 0.1 mol/L
