Answers:
Come on" too confident. Just think it a while, and consider that in a) adjectives Bi2O3 reacts, so just divide the mass by the molecular freight of Bi2O3. In b) just consider that you have two moles of Bi per respectively mole of Bi2O3, so multiply the result fo a) by 2. they teach these things at the kindergarden, you know? only kids use apples, sticks, ball, crayons or things alike.
