Find the mass of CO2 liberated when 4 moles of Carbon heated?​

Answer»

2.016l. is the answer. Explanation:CACO 3 ⇌CaO+CO 2 One mole of calcium CARBONATE on decomposition gives one mole of carbon dioxide.The molecular weight of calcium carbonate is 100 g/MOL.10 g calcium carbonate CORRESPONDS to 0.1 mol. It on decomposition will give 0.1 mol of carbon dioxide. But limestone is only 90% pure. Hence, 0.09 mol of carbon dioxide will be obtained.1 mole of carbon dioxide OCCUPIES 22.4 L at STP.Hence, 0.09 mol of carbon dioxide will occupy 0.09×22.4=2.016 L.
