What amount of dioxygen (in gram) contains `1.8 xx 10^22` molecules ?

A

`9.60`

B

`0.0960`

C

`96.0`

D

`0.960`

Text Solution

Verified by Experts

The correct Answer is:
D
`6.022 xx 10^23` molecules of `O_2 = 32 g `
` 1.8 xx 10^22 ` molecules of `O_2`
` = (32)/(6.022 xx 10^23) xx 1.8 xx 10^22`
= 0.960 g
