The compound C6H12O4 contains
A. 22 atoms per mole
B. twice the mass percent of H as compared to the mass percent of C
C. six times the mass percent of C as compared to the mass percent of H
D. thrice the mass percent of H as compared to the mass percent of O
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).
