Answer:

first option is not true

Explanation:

1 mole = 6.02 × 10²³ particles

C3H8 has 1 mole, so has 6.02 × 10²³ particles

5O2 has 5 moles so 5 × 6.02 × 10²³ = 3.01 × 10²⁴ particles

3CO2 has 3 moles so 3 × 6.02 × 10²³ = 1.806 × 10²⁴ particles

4H2O has 4 moles so 4 × 6.02 × 10²³ = 2.408 × 10²⁴ particles
