What is the mass of `12.044 xx 10^(23)` number of `O_(2)` molecules?

A

8 g

B

16 g

C

32 g

D

64 g

Text Solution

Verified by Experts

The correct Answer is:
D
Number of moles `=(12.044 xx 10^(23))/(6.022 xx 10^(23)) = 2`
`therefore` Mass of 1 mole of `O_(2)` molecule is 32 g.
`therefore` Mass of 2 moles of `O_(2)` molecules `=2 xx 32 = 64 g`
