Question

Calculate volume of co2 in litre produced when 25 gm of caco3 heated according to given equation caco3 it guse Cato + co2

Answer 1

Answer:

5.6 L Carbon dioxide at NTP

Explanation:

CaCO3--------> CaO + CO2 . According to the balanced chemical equation, 100 g of calcium carbonate gives 44 g of carbon dioxide. So, 25 g of calcium carbonate will give 11 g of carbon dioxide. Volume occupied by 11 g of carbon dioxide = No of moles × 22.4 L = ( given mass ÷ molar mass) x 22.4 L = (11 g ÷ 44 g) × 22.4 L = 5.6 L at NTP.
