How many moles of oxygen would contain 1.204 x 10^24 molecules? [Avogadro’s constant (NA) = 6.02 x 1023]

A. 1
B. 2
C. 3
D. 4

Correct Answer: Option B

B. 2

Explanation

6.02 x 10^23 molecules is 1mole
1.204 x 10^24 molecules will be……

1.204×10^24×1/6.02×10^23

1.204×10/6.02 = 12.04/6.02 = 2moles
