A saturated solution of KNO3 was prepared at 25° Cby dissolving 12.050 g KNO3 in water and the total volume of the solution is 10.5 mL. Determine the moles of KNO3 in the solution and enter it below. 0.11919 moles This number should have 5 significant figures. (enter in the number of sig figs in the box). Now determine the concentration of K+ and NO3 in the solution. Enter these values below. [K+] = 11.4 [NO3 ] = 11.4 These numbers should have 3 the number of sig figs in the box). M M ✔significant figures. (enter in Make a note of these concentrations, as you will use them in the next question.
