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.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
