Avogadros number was calculated as the number of?
atoms in 12 g of c-12
Avogadros number is the number what?
It is the number of fundamental particles - atoms or molecules - of a substance in 1 mole of that substance.
How many moles of atoms are in 6.0221023 atoms Ne?
ONE(1) mole. 6.022 x 10^(23) is the Avogadro Number. Which is a constant for the number of atoms of any element in one mole. So for Neon(Ne) the number represents one mole of neon atoms.
How many atoms are there in 55.8 grams of Fe?
Avogadros number (approximately). The atomic weight of iron is 55.845. Avogadros number , the number of atoms in a mole of an element, or the number of molecules in a mole of a compound is 6.023 X 1023
What is the relationship between avogadros number and one mole of any substance?
A mole of any substance has the Avogadro's number of such units. As an example, a mole of hydrogen atoms is equivalent to 6.022 x 1023 atoms.
What information does moles provide using Avogadros number?
1 mole has 6,022 140 857 (74).1023 molecules, atoms, ions.
How do you convert from atoms to mass and from mass to atoms?
moles to atoms you multiply the number of moles by avogadros number ex: 1.32 mol x (6.022 x 10^23 atoms)/mol mass to atoms you multiply the mass (in grams) times the molar mass of the element or compound (ex: N 14.01 mols/gram) then times avogadros number once you have the moles. ex: 45.6 g N x (14.01 mol/gram) x (6.022 x 10 ^23 atoms/mol) if it's a compound instead of an element, find the molar mass of the compound (the molar masses of all the elements in it added up) and multiply by it. ------------------------- Actually you are wrong, from mass to atoms you need to take the initial mass divide by the gram of the element that you are doing and multiply by the Avogadros number
Avogadros number of phosphorus P atoms would have a mass of?
By saying Avogadro's number of atoms, you are saying one mole (or 6.02 × 1023 atoms). And one mole of any elements is its atomic mass. Phosphorus' atomic mass is 31.0 grams
What is the relationship beween avogadros number and the mole?
Avogadro's number represents the number of units of a substance in one mole of the substance. These units may be electrons, atoms, ions, or molecules, depending on the substance.
How many Cu atoms in 5.33 moles CuCl2?
The number of copper atoms is 10,699.10e23.
How many atoms are in 1 mol Al2O3?
The number of molecules in a mole is Avogadros number, 6.023 X 1023 there are 5 atoms in each molecular formula unit so we then get 6.023x1023 x 5 =3.115 X 1024 atoms.
How do you convert atoms to grams with Avogadro's number?
divide the number of atoms by avogadros number (6.022*10^23), the resulting number is the number of moles you have. Multiply the number of moles of atoms by the molar mass (found on any periodic table) and the answer is how many grams of the substance you have.
