Using the Avogadro number , which is 6.022 x 10^(23) .
For ANY substance the number of atoms in ONE(1) mole is 6.022 x 10^(23).
Hence for FOUR($) moles it is 4 x 6.022 x 10^(23) =2.4.088 x 10^(24) atoms.
2.00 moles sodium (6.022 X 1023/1 mole Na) = 1.20 X 1024 atoms of sodium ---------------------------------------
To determine the number of atoms in 46.0 grams of sodium, you first need to calculate the number of moles of sodium present. With the molar mass of sodium being 22.99 g/mol, you can divide the given mass by the molar mass to find the number of moles. Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms by multiplying the number of moles by Avogadro's number.
The molar mass of sodium is 22.99 g/mol. To find the mass of 8 moles of sodium atoms, you would multiply the molar mass by the number of moles: 22.99 g/mol * 8 mol = 183.92 g. Therefore, the mass of 8 moles of sodium atoms is 183.92 grams.
0.34 moles Na2O (1 mole O 2-/1 mole Na2O)(6.022 X 1023/1 mole O 2-) 2.1 X 1023 ions of oxygen ================
To find the number of atoms in 28.75 g of sodium, you need to first calculate the number of moles of sodium using the molar mass of sodium (22.99 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of sodium to atoms. So, the number of atoms in 28.75 g of sodium would be approximately 7.45 x 10^23 atoms.
the constant Mole (mol): 6.02 x 10^23 are how many atoms you have per mol so the answer can be 7 mol atoms or 6.02 x 10^23 atoms per mol x 7 actual answer is 4.214 X10^24 atoms in 7 mol
0,2 mol sodium contain 1,204.10e23 atoms.
To find the number of sodium atoms in 0.2310 g of sodium, you need to convert the mass to moles using the molar mass of sodium (22.99 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. This calculation will give you the number of sodium atoms present in 0.2310 g of sodium.
In NaCl, the ratio of sodium to chloride atoms is 1:1. Therefore, in 2.35 mol of NaCl, there are 2.35 mol of sodium atoms. To find the number of sodium atoms, you would multiply the number of moles by Avogadro's number (6.022 x 10^23).
1 mole = 6.022 x 1023 4.8mol Na x (6.022 x 1023 atoms Na/mol Na) = 2.9 x 1024 atoms Na

2.00 moles sodium (6.022 X 1023/1 mole Na) = 1.20 X 1024 atoms of sodium ---------------------------------------
48,177 134 32.1023 atoms
Approx. 9.1024 atoms.
48,177 134 32.1023 atoms
To find the number of atoms in 23g of sodium, divide the mass of the sample by the molar mass of sodium (23g/mol). This gives you the number of moles, which you can then convert to atoms using Avogadro's number (6.022 x 10^23 atoms/mol). So, there are approximately 6.022 x 10^23 atoms in 23g of sodium.
1 mol has 6,022 140 857.10e23 atoms (The number of Avogadro).4 moles of sodium have 24,088 563 428.10e23 atoms.
