How would you determine the molecular formula of C4H9?

Answer 1

Just to retire this question ... are you sure that it is correctly posed...?

#C_4H_9# is not the formula of anything you could put in a bottle. It is the radical of some butane derivative, i.e. #C_4H_10#..

And so we have (possibly) #"tert-butyl radical"#...#(H_3C)_3C*#, the which is relatively long-lived...

On the other hand, you MIGHT have quoted an empirical formula of #C_4H_9#...to get the molecular formula, we need a measurement of the molecular mass...say we got a mass of #114.22*g*mol^-1#...this would correspond to a molecular formula of #C_8H_18#...and this is a saturated formula...

To determine the molecular formula of ( \text{C}_4\text{H}_9 ), we need to find the number of carbon and hydrogen atoms that make up the molecule. The molecular formula indicates the exact number of each type of atom in a molecule.

Since there are 4 carbon atoms (C) and 9 hydrogen atoms (H), the molecular formula of ( \text{C}_4\text{H}_9 ) is ( \text{C}_4\text{H}_9 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
