The compound CgHj^204 contains

The compound C6H12O4 (likely a typo for C6H12O4 in the prompt) has a molecular formula consisting of 6 carbon atoms, 12 hydrogen atoms, and 4 oxygen atoms. To find the mass percent, we use the atomic masses: Carbon (C) is 12 u, Hydrogen (H) is 1 u, and Oxygen (O) is 16 u [1]. The total mass of Carbon in the molecule is 6!! 12 = 72 u, and the total mass of Hydrogen is 12!! 1 = 12 u. Comparing these, the mass of Carbon (72 u) is exactly six times the mass of Hydrogen (12 u). Therefore, the mass percent of Carbon is six times the mass percent of Hydrogen. Option 1 is incorrect because 1 mole contains 22!! 6.022!! 10^23 atoms, not just 22 atoms. Options 2 and 4 are mathematically incorrect based on these mass ratios.
