4. The Na* concentration of a solution was determined by measurements with a sodium ion-selective electrode. The electrode system developed a potential of -0.2462 V when immersed in 10.0 mL of the solution of unknown concentration. After addition of 1.00 mL of 2.00 x 102 M NaCl, the potential changed to -0.1994 V. Calculate the Na* concentration of the original solution
