The human body is composed of approximately 18% carbon by weight. Carbon is a fundamental element in organic molecules, forming the backbone of proteins, carbohydrates, lipids, and nucleic acids. This percentage may vary slightly depending on individual factors such as body composition and diet, but carbon remains a crucial element for biological functions and overall health.

What is the percent composition of carbon in carbon monoxide?
To find the percent composition of carbon in carbon monoxide (CO), we first determine the molar mass of CO. Carbon has a molar mass of approximately 12.01 g/mol, and oxygen has a molar mass of about 16.00 g/mol, giving CO a total molar mass of 28.01 g/mol. The percent composition of carbon is calculated as (molar mass of carbon / molar mass of CO) × 100%, which results in (12.01 g/mol / 28.01 g/mol) × 100% ≈ 42.8%. Thus, the percent composition of carbon in carbon monoxide is approximately 42.8%.
