To calculate the mass of an atom,
1amu = 1.66*10^-24
and sodium has a mass of 22.99amu.
Therefore, 425 sodium atom would be
425*(22.99*(1.66*10^-24))=1.6219445~-20.
With the sig fig, the final answer is:
1.62*10^-20g

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.
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 grams of sodium carbonate contain 1.773 x 1017 carbon atoms?
To find how many grams of sodium carbonate contain 1.773 x 10^17 carbon atoms, you need to consider the molar ratio. Sodium carbonate (Na2CO3) has 1 carbon atom per molecule. Calculate the molar mass of Na2CO3, then use Avogadro's number to convert the number of carbon atoms to moles, and finally to grams.
How many atoms of sodium are there in 11.2 grams of sodium chloride?
There are 0.3 moles of sodium chloride in 11.2 grams. The molar ratio of sodium to sodium chloride is 1:1. Therefore, there are 0.3 moles of sodium atoms in 11.2 grams of sodium chloride, which is approximately 1.8 x 10^22 atoms of sodium.
How many atoms of sodium are present in Moles of sodium and what is the mass of it?

How many atoms of sodium are present in 3 mole 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 of sodium are present in 3 moles of sodium and what is the mass of it?
There are 1.8 x 10^24 atoms of sodium in 3 moles. The mass of 3 moles of sodium is 69 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 do you calculate a mole of an atoms weight in grams?
To calculate the weight of a mole of an atom in grams (molar mass), you add up the atomic masses of all the atoms in one mole of the substance. This can be found on the periodic table and is usually given in atomic mass units (amu). The molar mass is expressed in grams per mole.

Calculate the mass (in grams) of sodium sulfide that is needed to make 360ml of a 0.50 mol/L solution
What is the mass in grams of 9.76 x 1012 atoms of naturally occurring sodium?
The mass is 1,62.10e-11.
What is the mass of a sample of sodium that contains 2980 atoms?
Not much! 2980 atoms sodium [1 mole Na/6.022 X 1023 (atoms)][22.99 grams/1 mole Na] = 1.138 X 10 -19 grams sodium ====================
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 cell?
To calculate the mass of a cell, you would need to know the density of the cell and its volume. The mass can then be calculated by multiplying the density by the volume. Mathematically, Mass = Density x Volume.
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 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
