Saying that you have 2.0 moles of He is like saying that you have 2 dozen of something. We all know a dozen to be equal to 12, and in this case, the "dozen" is Avogadro's number (6.022*1023). If you multiply 2 dozen by 12, you'll have the number of whatever you're counting (24), and if you multiply 2.0 moles of He by Avogadro's number, you'll have the number of He atoms you're talking about.
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
2 x O3 = 6 of O so 6 x 6.023 x 1023 = 3.6138 x 1024
The number of chlorine atoms in 2,00 moles of CCl4 is 48,113.10e23.
6. 1 mole of CS2 contains 1 mole of carbon and 2 of sulfur.
The formula unit for calcium is a single atom. Therefore, the number of moles may be found by dividing the given number of atoms by Avogadro's number, or 1.999 moles.
Two moles of neon contain 12,044281714.10e23 atoms.
In Ca(HCO3)2, there are 2 moles of carbonate ions (CO3^2-), each containing 3 atoms. So there are 6 atoms in 1 molecule of Ca(HCO3)2. Therefore, in 4 moles of Ca(HCO3)2, there are 4 x 6 = 24 moles of atoms.
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
There are 9.12 moles of hydrogen atoms in 4.56 moles of NH2NH2. Each NH2NH2 molecule contains 2 hydrogen atoms.
2 moles C8H18 (18 moles H/1 mole C8H18) = 36 moles of hydrogen =================

1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
1,638 moles contain 9,864266723766.10e23 atoms.
How many moles are there in 9.0333x1024 atoms of helium
There are 4 phosphorus atoms in one molecule of copper phosphate (Cu3(PO4)2). Therefore, in 7.6 moles of copper phosphate, there would be 7.6 moles x 4 atoms = 30.4 moles of phosphorus atoms.
