GC Atomic Structure

The compound C6H12O4 contains

  1. 22 atoms per mole
  2. twice the mass percent of H as compared to the mass percent of C
  3. six times the mass percent of C as compared to the mass percent of H
  4. thrice the mass percent of H as compared to the mass percent of 0

Answer

There are 6.022×1023 entities in 1 mole. So, option A is incorrect.

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%

The correct option is C.
