Two bulbs `A` and `B` contains `16 g O_(2)` and `16 g O_(3)`, respectively. Which of the statements are ture?

A

Both bulbs contain same number of atoms

B

Both bulbs contain different number of atoms

C

Both bulbs contain same number of molecules

D

Bulb A contains `N_(A)//2` molecules while bulb B contains `N_(A)//3` molecules `(N_(A)="Avogardro's number")`

Text Solution

Verified by Experts

The correct Answer is:
A, D
(a) Number of `O_(2)` atoms `=16/32xx2xxN_(A)=1xxN_(A)`
(b) Number of `O_(3)` atoms `=16/48xx3xxN_(A)=1xxN_(A)`
(c) (i) Number of `O_(2)` molecules `=16/32xxN_(A)=1/2 N_(A)`
(ii) Number of `O_(3)` molecules `=16/48xxN_(A)=1/3 N_(A)`
(d) Is correct.
