What ammount of dioxygen (in gram) contains `1.8 xx 10^23` molecules ?

A

`96.0`

B

`9.60`

C

`0.960`

D

`0.0960`

Text Solution

Verified by Experts

The correct Answer is:
C
`6.022 xx 10^23` molecules are present in 32 g of `O_2`.
`:. 1.8 xx 10^23` molecules will be present in `=(32 xx 1.8 xx 10^22)/(6.022 xx 10^23)`g
`=0.960g " of " O_2`.
