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

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 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
How many atoms of sodium are there in 11.2 grams of sodium chloride?
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

Calculate Mass of cell?
To calculate the mass of the cell you will need to know the mass and atomic number of the element. Multiply the number of atoms by the amount of grams per mole to get the mass.
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
