How many o2 particles are in 2.50 of o2 at standard temperature and pressure (stp)? a. 4.15 x 10^22 particles b. 2.41 x 10^23 particles c. 5.02 x 10^23 particles d. 1.51 x 10^24 particles can you explain the answer ?

The correct answer is Option D.

Explanation:

To calculate the number of atoms, we take the help of mole concept.

According to mole concept:

1 mole of any element contains number of atoms.

We need to find the number of particles or atoms present in 2.5 mole of gas:

2.50 moles of gas will have =

Hence, the correct answer is Option D.
