Moles to Atoms | Formula, Calculation & Avogadro's Number from Chapter 2 / Lesson 4 213K What is the moles to atoms formula? How does one convert atoms to moles? Learn how to calculate the number of atoms in a sample from the relationship between moles and Avogadro's number. Related...
In salt (sodium chloride) there are equal numbers of sodium and chlorine atoms (NaCl), so the ratio is 1:1. We can easily explain this if chemical elements really exist as simple particles (atoms, in other words), which snap together like building blocks. Some substances are radioactive:...
How many atoms are in 1.44 moles of Mg? What mass in mg does 2.63 moles of Ni have? How many moles of magnesium (Mg) are there in 80.3 g of Mg? Convert 0.6319 grams of Mg to moles of Mg. How many moles are equal to 0.357 mg of NH2CH2COOH?

The Avogadro's number is the number of particles (molecules or atoms or ions or even photons) that are contained in one mole of a substance. It is equal to 6.023×1023particles per mole. Answer and Explanation: Here we are given the volum...
How many carbon atoms are in a 12 gram diamond? Avogadro's Number: The mass of one atom of an element is equal to the average atomic mass of the element divided by Avogadro's number, which is the number of particles (atoms, molecules, etc.) found...
Any two atoms that have the same number of protons belong to the same chemical element. But atoms with an equal number of protons can have a different number of neutrons, which are defined as being different isotopes of the same element. These isotopes are often unstable, and all those with...
5 moles of P4O10 * 4 P atoms= 20 moles of P (20 moles) * (6.023 * 10^23atoms/mole) = 1.2046 *10^25 atoms. Which doesn't make any sense to me at all. And then my teacher said something like I had the general IDEA of how to answer the problem (which I totally don't) ...
The number of particles present in one mole of any substance is equal to {eq}6.022\times10^{23}{/eq} particles. This is known as Avogadro's number which can be denoted as {eq}N_A{/eq}. The units may be in terms of atoms, ions, formula units, or molecules. ...
