How many particles are in 2.02 moles of dinitrogen monoxide (n2o)?

The answer to your question is:  1.21 x 10 ²⁴ particles of N₂O

Explanation:

Data

# of particles = 2.02 moles of N₂O

                           1 mol of N₂O 6.023 x 10 ²³ particles

                          2.02 moles       x

                                x = (2.02 x 6.023 x 10²³) / 1

                                x = 1.21 x 10 ²⁴ particles of N₂O
