To find the normality of a solution, we need to know the number of equivalents of the solute present in the solution. The equation for calculating the number of equivalents is: equivalents = mass (in grams) / equivalent weight The equivalent weight of HNO₃ can be calculated by dividing its molecular weight by the number of acidic hydrogen ions it can donate. HNO₃ has two acidic hydrogen ions, so its equivalent weight is: molecular weight / 2 = 63.012 / 2 = 31.506 Now we can calculate the number of equivalents in the solution: equivalents = 100.g / 31.506 g/equivalent = 3.17 eq Finally, we can calculate the normality of the solution: normality = equivalents / volume (in liters) = 3.17 eq / 0.5 L = 6.34 N Therefore, the answer is C (3.17 N).
