How many grams of quick lime is produced on heating 10g of marble? |
| Answer» PURE quicklime is calcium oxide, i.e., CaO. The atomic weights of calcium, carbon and oxygen are 40, 12 and 16 respectively. So 1 mole of limestone weighs 100 grams, 1 mole of quicklime weighs 56 grams. A “pure” conversion of 400 grams of limestone would, THEREFORE, yield 224 grams of quicklime. | |
