Option 1: This option states that the compound CgHj^204 contains 22 atoms per mole. However, based on the formula of the compound (CgHj^204), we can see that there are more than 22 atoms present. Therefore, this option is incorrect.

Option 2: This option states that the compound has twice the mass percent of H compared to the mass percent of C. To determine the mass percent, we need the molar masses of both elements. The molar mass of H is 1 g/mol, while the molar mass of C is 12 g/mol. Since the molar mass of C is greater than that of H, this option is incorrect.

Option 3: This option states that the compound has six times the mass percent of C compared to the mass percent of H. Again, to determine the mass percent, we need the molar masses. Since the molar mass of C is 12 g/mol and the molar mass of H is 1 g/mol, there is indeed a significant difference between the mass percent of C and H. Therefore, this option is correct.

Option 4: This option states that the compound has thrice the mass percent of H compared to the mass percent
