To calculate the number of moles of particles present in a sample, you need to divide the sample's mass by the molar mass of the particles. If you specify the particles as N'O, you should provide the molar mass of N'O for an accurate calculation.
There is no exact number of particles in the world as particles are constantly moving and changing. However, estimates suggest that there are around 10^80 particles in the observable universe.

There are 3 kinds of Sub-Atomic particles. These are Proton, Electron, Neutron.
At least two: 1 proton + 1 electron = Hydrogen atom

To see particles, such as individual cells or microorganisms, you would typically need a light microscope. However, to see smaller particles like viruses or nanoparticles, you would need an electron microscope.

There are many kinds of particles and many kinds of motion, so there is more than one answer to that question. In many cases, particle motion is explained by Newtonian mechanics. In other cases, you would need quantum mechanics or Einstein's theory of relativity, or the Maxwell equations if the particles are photons.

You need to know that one mole is 6.022 x 1023 particles (atoms, molecules, ions, formula units, etc...).

Radiation is the method of transferring heat that does not require particles. Radiation can occur through empty space because it consists of electromagnetic waves, such as light and infrared radiation, that can travel without the need for a medium.
To calculate the number of particles in 7.8g of NaCl, you first need to determine the number of moles using the molar mass of NaCl (58.44 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 particles/mol) to find the number of particles.
For boiling to occur, particles in a liquid need to gain enough kinetic energy to overcome the attractive forces holding them together. This causes the liquid to transition into vapor phase as the particles break free from the liquid's surface.
