Calculate number of grams of sodium in 7.2 grams of sodium phosphate?
The gram atomic mass of sodium is 22.9898, the formula of the least hydrated form of sodium phosphate is Na3PO4.10 H2O, and the gram formula unit mass of this sodium phosphate is 344.09. Therefore, the mass fraction of sodium in this sodium phosphate is 3(22.9898)/344.09 or about 0.20044, and the grams of sodium in 7.2 grams of this sodium phosphate is 1.44 grams of sodium, to the justified number of significant digits.
Calculate mass of 4.00 moles of sodium?
To calculate the mass of 4.00 moles of sodium, you can use the molar mass of sodium which is approximately 23 grams/mol. Therefore, 4.00 moles of sodium would have a mass of 4.00 moles * 23 grams/mole = 92 grams.
What would 124 sodium atoms weigh?
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.
How many atoms are present in 41.23 grams of sodium?
molar mass of sodium = 23 number of mols = mass/ molar mass therefore 46g of Na = 2 mol
How many atoms does sodium have if it has 23.0 g?
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
How many atoms of sodium are present in 3 moles of sodium and what is the mass of it?
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
If a sample of pure sodium has a mass of 8.2 grams and sodium has an average atomic mass of 22.99 gmol how many sodium atoms are there in the sample?
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.
Calculate number of grams of sodium in 7.2 grams of sodium phosphate?
The gram atomic mass of sodium is 22.9898, the formula of the least hydrated form of sodium phosphate is Na3PO4.10 H2O, and the gram formula unit mass of this sodium phosphate is 344.09. Therefore, the mass fraction of sodium in this sodium phosphate is 3(22.9898)/344.09 or about 0.20044, and the grams of sodium in 7.2 grams of this sodium phosphate is 1.44 grams of sodium, to the justified number of significant digits.
How many atoms of sodium are present in Moles of sodium and what is the mass of it?
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
How many atoms are present in 46.0 grams 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.

To calculate the mass of 4.00 moles of sodium, you can use the molar mass of sodium which is approximately 23 grams/mol. Therefore, 4.00 moles of sodium would have a mass of 4.00 moles * 23 grams/mole = 92 grams.
What is the total number of sodium atoms in 46.0 grams of sodium is?
The molar mass of sodium is 22.99 g/mol. To find the total number of sodium atoms in 46.0 grams of sodium, you would first convert grams to moles using the molar mass, then use Avogadro's number (6.022 x 10^23 atoms/mol) to find the total number of atoms. This would give you approximately 1.21 x 10^24 sodium atoms.

Mass in grams if the molar mass of sodium sulfate is 141.98 gramsmoles?
To calculate the mass in grams of sodium sulfate, we need to know the number of moles. Once we have the number of moles, we can multiply it by the molar mass to find the mass in grams. For example, if we have 2 moles of sodium sulfate, the mass would be 2 moles * 141.98 grams/mole = 283.96 grams.
