Detailed explanation-1: -Thus, mass percentage of carbon in carbon dioxide is 27.27 %.

Detailed explanation-2: -Percentage composition = 32/44 * 100 = 72.7 % (Answer)

Detailed explanation-3: -Carbon dioxide (CO2 ) constitutes about 0.03% (300 parts per million) of the atmospheric gases. Whereas, nitrogen comprises 70% and oxygen 21% of the atmospheric gases. Other gases, such as water vapors, nitric oxide, carbon monoxide, and others, make up 100%.

Detailed explanation-4: -The molecular mass of carbon dioxide is 44.01amu. The molar mass of any compound is the mass in grams of one mole of that compound. One mole of carbon dioxide molecules has a mass of 44.01g, while one mole of sodium sulfide formula units has a mass of 78.04g.
