3. What is the molecular formula of your assigned molecule (for example, the molecular formula
for glucose is C6H1206)?

Explanation:

In the figure attached, I have numbered the carbon atoms to permit to count them easily.

1.  Carbon atoms

Each vertex without a letter represents a carbon atom:

2. Hydrogen atoms

For each carbon subract 1 for each bond and subtract 1 for each group attached to it:

Total H atoms attached to C atoms:

Total H atoms in all: 16 + 2 = 18

3. Fluorine atoms

Count them:

4. Nitrogen atoms

Count them:

5. Oxygen atoms

Count them:

6. Molecular formula

Summary:

Molecular formula:

explanation:

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
