Calculate no: of particles in 4g of O2 molecule

1.	Calculate no: of particles in 4g of O2 molecule
Answer» Answer: 7.525 X 10^22 particles Explanation: the NUMBER of MOLES of O2 is 4/32= 0.125 moles given 1 mol ---> 6.02 x 10^23 particles 0.125 mol ---> x x/0.125 = 6.02x10^23/1 x= 7.525x10^22

Answer»

Answer:

7.525 X 10^22 particles

Explanation:

the NUMBER of MOLES of O2 is 4/32= 0.125 moles

given 1 mol ---> 6.02 x 10^23 particles

0.125 mol ---> x

x/0.125 = 6.02x10^23/1

x= 7.525x10^22
