A 15.00 mL solution of potassium nitrate (KNO^3) was dilutied to 125.0 mL, and 25.00 mL of this solution were then diluted to 1.000*10^3 mL. the concentration of the final solution is 0.00383 M. Calculate the concentration of the origanal solution Is it .00798M? When dealing with sig figs, is M counted as an exact number?
