What is the mass per cent of carbon in carbon dioxide? (i) 0.034% (ii) 27.27% (iii) 3.4% (iv) 28.7%

Correct Answer: (ii) 27.27%

Explanation: Carbon dioxide is a gas with a density of about 53% higher than that of dry air. Carbon dioxide molecules consist of a double carbon atom combined with two oxygen atoms. It occurs naturally in the earth’s atmosphere like trace gas. And, the mass percentage of carbon in carbon dioxide is 27.27%.
