Given:
Mass of empty dry crucible = 0.5 g
so when we ass sodium bicarbonate to it, the mass will surely increase. But according to your question it is still 0.5 g. Therefore you have not added anything to the crucible. In which case, mass of sodium bicarbonate used = 0 g
yield of sodium carbonate = 0 g
% yield of sodium carbonate = 0
But, Let us assume the mass of crucible + mass of sodium bicarbonate is = ( 0.5 + a ) g
Since, mass will increase for sure if we add something.
