You have to find the molecular weight of the formula using the Periodic Table. For example CH4 is 12+1+1= 14.0006+owerasabc.at.omc X5 24871283468`26478`6498`26487`268347628u q2tyr8136er8ye8 . The molecular weight is equal to grams per mole. So:
MW = g/mole
To find the number of moles in one gram then simply divide 1 by the molecular weight: 1/MW.
Now you know how many moles you can convert that to number of atoms by multiplying it by Avogadro's number: 6.022 x 10^23

What is the molecular weight of fenol?
Phenol. C6H5OH 6 carbon atoms = 72.06 grams 6 hydrogen atoms = 6.048 grams 1 oxygen atom = 16.0 grams ===========================add = 94.108 grams per mole ---------------------------------
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 atoms of hydrogen are in 5 grams of water?
6.6x1022 per gram of water
Can explain how to get the molecular of mass of CO2?
Just add the grams per mole mass of the constituent atoms. C---carbon = 12.01 grams 2 O---2 oxygens = 16.0 grams each, or 32.0 grams ------------------------------------------------------------------------+ = 44.01 grams per mole for CO2 ( carbon dioxide )
Which has the greatest number of atoms- 3.5 grams of helium or 3.5 grams of lithium?
Helium because it has fewer atoms, so there are more atoms needed to have 3.5 grams of it.
What is the molecular weight of fenol?
Phenol. C6H5OH 6 carbon atoms = 72.06 grams 6 hydrogen atoms = 6.048 grams 1 oxygen atom = 16.0 grams ===========================add = 94.108 grams per mole ---------------------------------
How many atoms does 100 grams of gold have?
Gold has a molar mass of 196.96655 grams per mole. 100 grams then is equal to .508 moles which makes 3.059 E23 atoms of gold.
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 atoms of hydrogen are in 5 grams of water?
6.6x1022 per gram of water
How do you atoms to grams?
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 SubstanceTake 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
How many atom are in 143g of calcium?
First, look up the atomic mass of calcium: 40.08 grams per mole 143 grams, divided by 40.08 grams per mole, results in 3.57 moles. Since you specifically asked for the number of ATOMS, multiply by Avogadro's number, 6.02 x 10-to-the-23rd-power atoms per mole. Final answer: 2.15 x 10-to-the-24th power atoms.

Just about 6.022 X 1023 atoms of sulfur. Sulfur is 32.07 grams per mole.
How do I find the density in grams per 120 milliliters to 40 grams of corn syrup?
It is 40/120 = 0.33... grams per mL.
How many atoms does 32 g sulfur contain?
Just about 6.022 X 1023 atoms of sulfur. Sulfur is 32.07 grams per mole.
How many atoms 32 g of sulfur contain?
Just about 6.022 X 1023 atoms of sulfur. Sulfur is 32.07 grams per mole.
Can explain how to get the molecular of mass of CO2?

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
