From ideal gas equation that is PV=nRT
n(number of moles)=PV/RT
P=760 torr
V=4.50L
R(gas constant =62.363667torr/l/mol
T=273 +273=298k
n is therefore (760torr x4.50L) /62.36367 torr/L/mol x298k =0.184moles
the molar mass of NO2 is 46 therefore density= 0.184 x 46=8.464g/l
The mass of an electron can be expressed in the box as 
.
Further explanation:
Atom is the smallest particle that can be present in any element. It is also known as the building unit of matter. Each atom has a central part that is known as the atomic nucleus. There are three subatomic particles that constitute the atom. These particles are protons, neutrons, and electrons. The atomic nucleus consists of protons and neutrons, both are collectively called nucleons. Electrons revolve around the nucleus of an atom in definite orbits.
Protons are positively charged subatomic particles, electrons are negatively charged and neutrons have no charge. Since electrons carry a unit negative charge, these create an electric field around them. These also participate in nuclear reactions. The mass of an electron 
is 
, that of protons is 
and that of neutrons is 
. The electrons are responsible for chemical properties of elements. The distribution and arrangement of electrons is used to predict whether the element will be inert or reactive.
Therefore the required answer is .

The sensory neurons within the olfactory organ are stimulated by Chemicals in the air.
Sensory neurons are the neurons that take up the signal from the receptors to the Central Nervous system (CNS)
Olfactory organ is the organ which is capable to sense smell i.e. Olfaction.
The Chemicals present in the air stimulates the sensory neurons present withing the olfactory organ consisting of olfactory epithelium. The cilia present in the epithelium recognizes the chemical present.
The neurons form connections of neuron to the olfactory bulb.
It is a mass of tissue that is round in shape that comprises of several kinds of cells of neurons that are capable to sense smell. It is necessary to sense smell properly.
Odorants are the compound that consist of an odor which get detected by the sensory neurons to carry out olfaction. They activate olfactory receptors and send signals to olfactory bulb.
