Question

Calculate the number of particles for 32 grams of oxygen atom

Answer 1

12.04 × 10²³ number of particles  

Explanation:

Molecular weight of Oxygen = 16

According to Avogadro's law,

16 g of oxygen has 6.022 × 10²³ number of particles

32 g of oxygen will have x number of particles

hence x = 6.022 × 10²³ × 32/16

              = 12.04 × 10²³ number of particles
