Final answer:
To determine the number of sp3 atoms in a molecule, its structure needs to be known and the sp3 hybridized carbon atoms need to be counted.
Step-by-step explanation:
The molecule mentioned in the question is not provided. However, based on the information given, we can determine the number of sp3 atoms present.
In a molecule, sp3 hybridization occurs when a carbon atom forms four sigma bonds using one s orbital and three p orbitals. The carbon atom is then surrounded by four regions of electron density, forming a tetrahedral shape with bond angles of 109.5 degrees.
To determine the number of sp3 atoms, we would need to know the molecule's structure and count the carbon atoms that are sp3 hybridized.
