In I molecule of C₃H₈, the ratio of Carbon to Hydrogen atoms = 3 : 8
C: H = 3:8
C : 4.64*10²⁴ = 3:8
C / (
4.64*10²⁴) = 3 / 8
C = (3/8) * (4.64 * 10²⁴)
C = 1.74 * 10²⁴
The sample contains
1.74 * 10²⁴
C atoms.

To calculate the number of carbon atoms in the sample of C3H8, the subscipts of the chemical formula is important since this gives the proportion of an element in a compound.
4.64 × 10^24 H atoms ( 3 atoms C / 8 atoms H ) = 1.74 x 10^24 atoms C
