You find the number of atoms from the number of grams of a given substance by:
Find the Moles of the Substance by multiplying the grams of the substance by the molar mass of the substance. ( Molar mass equals mass of substance per 1 mole of substance.)
Grams x Molar Mass of Substance = Moles of Substance
Take the moles of the substance and multiply it by Avogadro's Number (the number of atoms in 1 mole of substance, or simply 6.022x1023).
Moles of Substance x Avogadro's Number (6.022x1023) = atoms of Substance

What has more atoms 2.88 grams of helium atoms or 16.4 grams of zinc atoms?
2,88 grams of helium have 3,761.1023 atoms; 16,4 grams of zinc have 1,511.1023 atoms.
How many oxygen atoms are there in 3.45 grams of H2O?
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
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 many hydrogen atoms are in 1.25 grams of CH4?
1,25 grams of CH4 contain 0,156696.10e23 atoms.
What is the of 3.09x10 24 atoms of sulfur in grams?
3,09x10e24 atoms of sulfur in grams is equal to 164,65 g.
How many hydrogen atoms are in 45.0 grams of hydrogen gas?
45,0 grams of hydrogen gas have 135,5.10e23 atoms.
How many grams atoms are in 100 of sulfur?
The molar mass of sulfur is approximately 32 grams per mole. Therefore, 100 grams of sulfur would contain approximately 3 moles of sulfur atoms (100 grams / 32 grams/mole). To find the number of atoms, you would then multiply the number of moles by Avogadro's number (6.022 x 10^23 atoms/mole) to get the total number of sulfur atoms in 100 grams.
How many moles on 738 grams or iron and how many atoms?
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
How many atoms are in 21.84 grams of C?
There are approximately 3.633 x 10^23 carbon atoms in 21.84 grams of carbon.
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.
How many atoms are in 300 grams of gold?
There are approximately 1.93 x 10^23 atoms in 300 grams of gold. This is calculated using Avogadro's number (6.022 x 10^23 atoms/mole) and the molar mass of gold (197 grams/mole).
Which has the greatest number of atoms- 3.5 grams of helium or 3.5 grams of lithium?
3.5 grams of lithium would have a greater number of atoms because lithium is heavier than helium. Each element has a different atomic mass, so the same weight of each element will contain a different number of atoms.
