Use the p table and take 2 times the atomic mass of Fe and then 3 times the atomic mass of C and 9 times the atomic mass of O
So I know that O= 16×9
C=12×3
Fe= Then add all the products up to find molar mass
it's called an ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable

You have 1.42mol O2.
If 1mol is 6.022*1023 molecules of O2, then 1.42mol O2 is equal to 1.42*6.022*1023 molecules of O2. This gives a total of approx. 8.55*1023 molecules of oxygen gas.
