Explanation / Answer

Ans. Mass of inert binder = Net mass of Tablet – Mass of active component

                                                = 2.22 g – 1.062 g                            ; [1 g = 103 mg]

                                                = 1.138 g = 1138 mg                                

% mass of inert binder = (Mass of inert binder / Net mass of tablet) x 100

                                                = (1.138 g / 2.22 g) x 100

                                                = 51.72 %

Note: Please make correction:

I. mg of active ingredient = 1000 mg = 1.0 g but NOT 0.1 g                ; [1 g = 1000 mg]

Rest of the calculation is correct.
