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 contains same number of atoms.

B

Both bulbs contains 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)` = Avogadro's number).

Text Solution

Verified by Experts

The correct Answer is:
A, D

a. Number of of `O_(2)` atoms `= (16)/(32) xx 2 xx N_(A) = 1 xx N_(A)`
b. Number of of `O_(3)` atoms `= (16)/(48) xx 3 xx N_(A) = 1 xx N_(A)`
c. i. Number of of `O_(2)` Molecules `= (16)/(32) xx N_(A) = (1)/(2) N_(A)`
ii. Number of of `O_(2)` molecules `= (16)/(48) xx N_(A) = (1)/(3) N_(A)`
(d) is correct.
