How many atoms of carbon does this molecule have?
1) 2 atoms
2) 4 atoms
3) 1 atom
4) 6 atoms

This molecule has 4 atoms of carbon.

are you sure it's not four?

Yes, you are correct. I apologize for the error. This molecule has 4 atoms of carbon.

To determine the number of carbon atoms in the molecule, we need to count the carbons in the structure. Looking at the model, we can see that there are two carbon atoms connected by a single bond. Therefore, the correct answer is:

2) 4 atoms

To determine how many atoms of carbon are present in the molecule, we need to analyze its structure. In this case, we have a central carbon (C) atom connected to four other atoms: two hydrogen (H) atoms and two more carbon atoms.

To count the number of carbon atoms, we count all the individual carbon atoms in the molecule. In this case, there are two carbon atoms connected to the central carbon atom. So in total, this molecule has 3 carbon atoms.

Therefore, the correct answer is:

4) 3 atoms
