Number of particles (atoms) =
Avogadro's number (parts per mole) * [ mass (grams) / molar mass (grams per mole) ]
So: N = 6.02*10+23 * 23.0 / 22.99 = 6.02*10+23atoms sodium
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.
23 g of sodium metal will have 6.023 x 1023 atoms (or 1 mole of atoms)
To find the number of atoms of sodium in 46.00 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) to convert the moles to atoms. Finally, multiply the number of moles by Avogadro's number to get the number of atoms of sodium.
Sodium has an atomic mass of 29.990 g/mol. This means that 124 sodium atoms have a mass of 3718.76 amu, if the isotopes follow the average. To find in grams, the following must be used: 124 sodium atoms equal 2.0598 * 10-22 moles, so 124 sodium atoms have a mass of 6.177 *10-21 grams.
This problem requires the atomic masses of each element involved. Then add them together to get the total molecular mass. If you take sodium's weight and divide it by the total mass, then you should have the percent of sodium in sodium chloride. Na- 23.0 Cl- 35.5 NaCl- 58.5 grams 23.0 / 58.5 × 100= 39.3% Na in NaCl Now we need to find the total number of atoms in the whole compound. Take the grams and convert it to atoms using Avogadro's constant. 11.2 g Na × (6.02 × 1023 atoms) / (23.0 g) Na = 2.93 × 1023 atoms If that is the total mass, then we know that 39.3% of it has to be sodium 39.3% of (2.93 × 1023)= 1.15 × 1023 atoms Na
41,1 g of sodium sulfate (Na2SO4, anhydrous) contain 10,455.10e23 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.
23 g of sodium metal will have 6.023 x 1023 atoms (or 1 mole of atoms)
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.
There are 9 oxygen atoms in 5.00 g of sodium dichromate Na2Cr2O7. This can be calculated by finding the molar mass of Na2Cr2O7 and then determining the moles of oxygen present, which is then used to find the number of atoms.
1, because Na does not have a number after it.
In one mole of sodium dichromate (Na2Cr2O7), there are 7 oxygen atoms. To find the number of moles in 7.00 g, you need to divide 7.00 g by the molar mass of Na2Cr2O7 to find the number of moles of Na2Cr2O7. Then, multiply the number of moles by 7 to find the number of oxygen atoms in 7.00 g of sodium dichromate.
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.
To find the number of atoms of sodium in 46.00 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) to convert the moles to atoms. Finally, multiply the number of moles by Avogadro's number to get the number of atoms of sodium.
To calculate the number of sodium atoms in the sample, first find the number of moles in the sample by dividing the mass (8.2 g) by 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. Therefore, there are approximately 2.71 x 10^23 sodium atoms in a sample weighing 8.2 grams.
The molar mass of sodium (Na) is 22.99 g/mol. Therefore, the mass of 8 moles of sodium atoms would be 8 moles x 22.99 g/mol = 183.92 grams.
No, the number of atoms in a substance is determined by Avogadro's number (6.022 x 10^23 atoms/mol). To calculate the number of atoms, you need to convert the mass of each element to moles first using their respective molar masses, which are 22.99 g/mol for sodium and 238.03 g/mol for uranium.
