Question

3.25 * 10 ^ 24 molecules of dinitrogen pentoxide would be how many moles?

Answer 1

5.39

full answer: 5.396878114

Step-by-step explanation:

divide 3.25*10^24 over 6.022*10^23(which is a mole of anything in particles)

Answer 2

Answer: 5.4 moles

Step-by-step explanation:

Dinitrogen pentoxide has a chemical formula of N2O5

Now, based on Avogadro's law:

1 mole of any substance has 6.02 x 10^23 atoms

So, 1 mole of N2O5 = 6.02 x 10^23 molecules

Z moles of N2O5 = 3.25 x 10 ^ 24 molecules

To get the value of Z, cross multiply:

(3.25 x 10^24 molecules x 1mole) = (6.02 x 10^23 molecules x Z moles)

3.25 x 10^24 = (6.02 x 10^23 x Z)

Z = (3.25 x 10^24) ➗ (6.02 x 10^23)

Z = 5.4 moles

Thus, there are 5.4 moles of Dinitrogen pentoxide.
