Answer:

(4) 266 moles

Explanation:

We have Dinitrogen Pentoxide N2O5

6.41*10^25 molecules are given

No of Moles of N2O5 = \frac{No of Molecules }{Avogadro's Number}

                                     = \frac{6.41 * 10^25}{6.022*10^23}

                                      = 106.5 mol

Now using Unitary Method

2 Mole of Nitrogen pentoxide require 5 mole of Oxygen to form N2O5

1 mole of N = \frac{5}{2}*O

In 106.5 mole of N  = \frac{5}{2}*106.5 = 266.25 mole

So, 6.41*10^25 molecules of N2O5 will require 266.25 mole of Oxygen atoms.
