One mole of oxygen gas at STP is equal to ......

A

`6.022xx10^(23)` molecules of oxygen

B

`6.022xx10^(23)` atoms of oxygen

C

16 g of oxygen

D

32 g of oxygen

Text Solution

Verified by Experts

The correct Answer is:
A, D
At STP 1 mole of `O_(2)` gas`=6.022xx10^(23)` molecules of `O_(2)=32g` of `O_(2)` thus, 1 mole of oxygen gas is equal to molecular weight of oxygen as well as Avogadro number.
