WebThe molecular weight of calcium carbonate is 1 0 0 g/mol. 1 0 g calcium carbonate corresponds to 0. 1 mol. It on decomposition will give 0. 1 mol of carbon dioxide. But limestone is only 9 0 % pure. Hence, 0. 0 9 mol of carbon dioxide will be obtained. WebSet a lump of chalk (calcium carbonate) on a gauze. If your gauze has a coated central circle, use the edge where there is no coating. Heat the chalk very strongly for 5–10 …
