When the mixture of sodium carbonate and sodium bicarbonate (2 g) is heated, then sodium bicarbonate decomposes to give sodium carbonate, water and carbon-di-oxide, which are evolved as gases. Therefore the loss in the weight (0.124 g) of the mixture will be due to evolution of theses gases

 

62 g (18g+44g) of gas is produced from 168 g of Sodium Bicarbonate.

Therefore, 0.124 g of gas will be produced form (0.124x168)/62 = 0.336 g of Sodium Bicarbonate.

The weight of sodium bicarbonate is 0.336 g, so, weight of sodium carbonate will be (2g-0.336g) = 1.664g.
