A 2.0 g sample containing MnO 2 is treated with HC1 liberating C1 2 . The C1 2 gas is passed into a solution of KI and 60.0 mL of 0.1 M Na 2 S 2 O 3 is required to titrate the liberated iodine. The percentage of MnO 2 in the sample is__________. (Nearest integer) [Atomic masses (in u) Mn = 55; Cl = 35.5; O = 16, I = 127, Na = 23, K= 39,8 = 32]
