57. [Algorithmic] Sulfamic acid, HSO,NH, (molar mass = monoprotic acid that can be used to standardize a strong base: 97.1 g/mol), is a strong HSO,NH,(aq) + KOH(aq) → KSO,NH,(aq) + H,O(1) A 0.179-g sample of HSO,NH, required 19.4 mL of an aqueous solution of KOH fo complete reaction. What is the molarity of the KOH solution? a) 9.25 M b) 9.50 x 10-5 M c) 0.0950 M d) 0.194 M e) none of these
