Hey !
Here is your answer !!

0.5 moles of K2Cr2O7,

Then you just multiply the number of moles by avogadro's number.

= (0.5)(6.022x1023)

= 3.011x1023molecules.

Since there are 11 atoms per molecule (2+2+7), then you just multiply 3.011x1023 by 11
========>>>>>>

 3.3121x1024 atoms.

Hope it helps !
