What does Avogadro's number of representative particles equal to?
one mole.
How did avogadros number got its name?
Avogadro's number, approximately (6.022 \times 10^{23}), is named after the Italian scientist Amedeo Avogadro, who, in the early 19th century, proposed that equal volumes of gases at the same temperature and pressure contain an equal number of molecules. Although he did not directly calculate this number, his work laid the foundation for understanding the mole concept and the relationship between mass and the number of particles in a substance. The number was later named in his honor as it became a fundamental constant in chemistry.
Are there any numbers named after people?
Yes, there are numbers that are named after people. My personal favorite is Avogadro's Number, which is approximately 6.02 x 1023 and which is an important number for chemists, which is equal to the number of particles in a mole.
Do Polar molecules have an equal number of positive and negative particles?
It depends on how you define particle. For example, if ATOMS are considered particles, then the answer is no. Take Water, one of the most simple molecules. It contains one Oxygen atom (charge -2) and two Hydrogen atoms (charge+1 each). If you consider that atoms are really made of protons, neutrons, and electrons, ALL stable molecules, polar or not, have an equal number of protons (postive charged particles) and electrons (negative charged particles), else they would not be stable.
What is 29.47 equals?

Avogadros number of representative particals is equal to one?
Avogadro's number is the number of particles (atoms, molecules, ions, etc.) in one mole of a substance, which is approximately 6.022 x 10^23. Therefore, 1 mole of any substance contains Avogadro's number of representative particles.
What does Avogadro's number of representative particles equal to?
one mole.
How many moles is 2.17x10 representative particles of bromine?
Since one mole is equal to 6.022x10^23, there are .36 moles in 2.17x10 representative particles of bromine. A mole is a measure used to make atomic calculations for density.
One mole is equal to how many grams?
Its avogadros number which is 6.02 X 10^23 g/mol
How many representative particles equal a mole?
6.02 x 10^23 RP. This is called Avogadro's number.
What evidence supports avogadros hypothesis?
PV/NrT, pressure(volume)/amount(constant)(temperature). When your temperature, volume, and pressure are all the same, you get the same number of particles. This is avogadros hypothesis. Let's say that you have to balloons. They have the same temperature, volume, and pressure. If you weigh the gases in the balloon, you will find that there is the same amount of particles. In fact Dalton did this was able to find out the amount of particles (atoms) by the mass of objects.

What does the mass number equal?
The total number of subatomic particles in the nucleus
Why are ions charged particles !?
The number of electrons does not equal the number of protons.
What is the best summary of avogadros law?
Equal amounts of all gases have the same volume at the same conditions.
What are the avogadros inventors?
Avogadro's law, which states that equal volumes of gases at the same temperature and pressure contain an equal number of molecules, was formulated by the Italian scientist Amedeo Avogadro in 1811. While Avogadro himself is credited with the concept, the actual term "Avogadro's number," representing the number of particles in one mole of a substance (approximately (6.022 \times 10^{23})), was named in his honor later on. Avogadro's contributions were pivotal in the development of molecular theory and stoichiometry in chemistry.
Which two particles in a atom are equal in number?
Electrons and protons.
