It's a cyclohexane ring with an ethyl group at 1 and a methyl group at 3. The Ethyl group is bigger and more important group get's the first position.
1-ethyl-3-methylcyclohexane
I can give you a clue of getting mass. if it is the atomic number is even multiply by 2 but if the atomic number is odd multiply by 2 and add 1
sodium atomic number = 11 so mass = 11*2 +1 = 23
oxygen. atomic number = 8 so mass = 8*2 = 16
carbon atomic number = 6 so mass = 6*2 = 12
Answer:
Hydrogen (H) Sulfur(S) and Oxygen(O)

Answer:
empirical formula
This also means that in one mole of iso-octane, there are 8 moles of carbon and 18 moles of hydrogen. The empirical formula is the simplest whole-number ratio of atoms in the compound. For iso-octane, the empirical formula is C4H9. Notice that the molecular formula is twice that of the empirical formula.
