Acetaldehyde is an organic compound (a compound containing C atoms) composed of a carbonyl group. On the other hand, a carbonyl group is a functional group containing C = O. The hybrid orbitals of a compound determines the number pi and s orbitals in the electronic configuration. For a single bond, there are two s orbitals. For double bonds, on the other hand, the number of s orbital bond is 1 while the number of pi bonds is 2. For triple bonds, there are three pi bonds present in the cloud.
Thus for a c = O bond, the atomic orbital configuration is sp3 containing 1 s orbital and 2 pi bonds.

Answer:
1.2044 × 10^24 oxygen atoms
Explanation:
To convert from moles to atoms, simply multiply the number of moles by Avogadro's number, 6.022 × 10^23
2 × 6.022 × 10^23 
=1.2044 × 10^24
 
        
             
        
        
        
Use n1/V1 = n2/V2
.1/2 = .4/V2
.1V2 = .8
V2 = 8 L or D
