1mol Na in grams = 22.989770g
1mol Na atoms = 6.022 x 1023 atoms
1 x 1020 atoms Na x 1mol/6.022 x 1023 atoms x 22.989770g/mol = 0.004g Na (rounded to one significant figure)

What is the mass in grams of 2x1012 atoms of potassium?
What is the mass, in grams, of 2 × 1012 atoms of potassium?
How many hydrogen atoms are in 2.99 pg of this compound?
The molar mass of hydrogen is 2.01588 g/mol Avogadro's number is 6.022141 x 1023 molecules/mol 2.99 picograms * 1mol/2.01588 grams * 1x10-12 g/pg * 6.022141x1023 molecules/mol * 2 atoms/molecule = 1.79x1012 atoms
How do you calculate a mole of an atoms weight in grams?
you take the atomic mass of the atom (or molecule) and you have the mass in grams
How can you fine the mass of mole of atoms of atoms of an element in grams?
Simple: the atomic weight expressed in grams. Example for dysprosium - 162,500 grams.
What is the mass in grams of 6.022 x 1023 N atoms of mass 14.01 amu?
The molar mass of any element is its atomic weight (amu) in grams, and 1 mol of any element is 6.022 x 1023 atoms. Therefore, the mass in grams of 6.022 x 1023 atoms of N = 14.01g N.
What is weight in chemistry?
Weight is often measured in grams. Or any smaller or larger unit of weight. For instance: 1 picogram is 1x10-12 grams 1 nanogram is 1x10-9 grams 1 microgram is 1x10-6 grams 1 milligram is 1x10-3 grams 1 centigram is 1x10-2 grams 1 decigram is 1x10-1 grams 1 decagram is 1x101 grams 1 hectogram is 1x102 grams 1 kilogram is 1x103 grams 1 megagram is 1x106 grams 1 gigagram is 1x109 grams and 1 tetra gram is 1x1012 grams. The atomic weight of an element is the relative atomic mass of an atom of a particular element.

What is the molecular mass of substance each molecule of which contain 4 carbon atoms and 10 hydrogen atoms.?
This would be C4H10 and the molecular mass is (12x4) +(1x10) = 48 + 10 = 58g/mole.
How to convert grams to atoms?
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
How do you calculate a mole of an atoms weight in grams?
you take the atomic mass of the atom (or molecule) and you have the mass in grams
How can you fine the mass of mole of atoms of atoms of an element in grams?

What is the mass of 5.0g of Fe how many atoms are present?
For this problem, the atomic mass is required. Take the mass in grams and divide it by the atomic mass. Then multiply it by Avogadro's constant, 6.02 × 1023.5.0 grams Fe / (55.9 grams) × (6.02 × 1023 atoms) = 5.38 × 1022 atoms
What is the mass in grams of 6.022 x 1023 N atoms of mass 14.01 amu?
The molar mass of any element is its atomic weight (amu) in grams, and 1 mol of any element is 6.022 x 1023 atoms. Therefore, the mass in grams of 6.022 x 1023 atoms of N = 14.01g N.
How many atoms of gold are in 5 grams of gold?
