What is the volume occupied by 4.4 grams of Carbon dioxide gas at STP ?
Volume occupied by one mole of any gas at STP is called molar volume. It is exactly 22. 71 L. 1 mole of carbon dioxide = 44 gram (Molecular mass) 44 grams of carbon dioxide occupies the volume = 22.71 L No. of moles of carbon dioxide = Mass/ Molecular mass = 4.4 g /44 g = 0.1 mole Volume occupied by 0.1 mole Carbon dioxide = (0.1 mol X 22. 71 L) / 1 mol = 2.271 L
