Question

give me the answer of this question​

Answer 1

According to the concept of moles, 6.022×10^23 molecules of oxygen weigh = 32g

Thus, mass of 1 molecule of oxygen= 32/6.022×10^23

= 5.32× 10^-23 g

If a mile contained 10^20 particles, the mass of one mole i. e. 10^20 particles = 5.32×10^-23 × 10^20

Thus, the molecular mass of oxygen is= 5.32×10^-3 grams
