How many molecules of dinitrogen pentoxide are in 0.27 moles of dinitrogen

pentoxide?

1.6 * 10²³ molecules of N2O5

Explanation:

To find the amount of molecules from the amount of moles of a substance we simply multiply the amount of moles by Avagadro's number.

0.27mol * 6.02*10²³ = 1.6 * 10²³ molecules of N2O5
