The number of moles of oxygen that are in 3.7 moles of C8H11NO2 is 7.4 moles
Explanation
- Determine the number oxygen atom in C8H12NO2
- The number of oxygen atom in C8H11NO2 are 1 x2= 2 atoms
- since they are two atoms of oxygen in C8H11NO2 the number of oxygen moles are therefore= 2 x3.7= 7.4 moles
