The type of chemoreceptor responsible for our sense of smell is called olfactory receptor. It is also known as odorant receptor, these are found in a small patch of tissue high inside the nose. These cells directly connected to the brain.
Force is mass × acceleration and it is measured in Newtons.
Mass = 3kg
Acceleration = 9m/s²
F = ma
F = 3×9
F = 27Newtons.
