Generally, around 20 million.
In the olfactory epithelium, which is in turn located high up in the nasal cavity. Additionally, some odor receptors are present in human sperm, which allow for positive chemotaxis.
Olfactory hair cells
Olfactory bulbs are smaller in human's because sheep's rely on their sense of smell more than humans do. Where as human's rely on seeing more then smell.
Retinal Cells, Olfactory epithelium Cells
the receptor cells in the olfactory membrane.....
The olfactory epithelium contains 10 million olfactory cells. Since you have two nostrils, you have a total of 20 million smell cells!

The olfactory epithelium occupies an area of about 5 cm2 in the roof of the nasal cavity. The specialized receptor cells in the olfactory epithelium are surrounded by supporting cells, non-sensory epithelial cells. The olfactory receptor cells are bipolar neurons whose olfactory cilia extend outward from the epithelium.
Olfactory nerves, definetly. We're studying this currently in my grade.

Smelling
These cells are called sustentacular cells or supporting cells. They surround and support the olfactory receptor cells in the olfactory epithelium. They provide physical support, nourishment, and electrical insulation to the olfactory receptor cells, helping to maintain their function.
In the olfactory nerves of the nose
The olfactory bulb can detect the smell of odor particles.
