Answer» Correct option C. six times the mass percent of C as compared to the mass percent of H Explanation: There are 6.022 ×1023 entities in 1 mole. Atomic mass of Carbon = 12 Atomic mass of Hydrogen = 1| Atomic mass of Oxygen = 16 Molecular mass = (6 × 12) + (12 × 1) + (4 × 16) = 72 + 12 + 64 = 148 Mass percentage of carbon = 72/148 = 49% Mass percentage of hydrogen = 12/148 = 8% Mass percentage of oxygen = 64/148 = 43% Hence, correct option is (C). |
