How many atoms are in 0.05 moles of xenon gas at stp?

2.2 x 10^23

3.0 x 10^22

6.0 x 10^23

3.0 x 10^24

Option (b) is the correct answer.

Explanation:

According to the mole concept there are atoms present in 1 mole of a substance.

Mathematically,    1 mole = atoms or molecules

Therefore, number of atoms present in 0.05 moles of xenon are as follows.

                   = atoms

or,                = atoms

Thus, we can conclude that there are atoms present in 0.05 moles of xenon gas at STP.
