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

To find the number of atoms in a given mass of a substance, you can use the formula: number of atoms = (mass in grams / molar mass) * Avogadro's number. The molar mass is the mass of one mole of the substance in grams, and Avogadro's number is approximately 6.022 x 10^23 atoms/mol.
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 ---------------------------------
There are 2 oxygen atoms in one molecule of CaCO3. To calculate the number of oxygen atoms in 50 grams of CaCO3, you first need to find the number of moles of CaCO3 using its molar mass. Then, multiply the number of moles by the number of atoms of oxygen per molecule of CaCO3 (2) to find the total number of oxygen atoms.
2,88 grams of helium have 3,761.1023 atoms; 16,4 grams of zinc have 1,511.1023 atoms.
To find the number of atoms in 175 grams of calcium, you first need to calculate the number of moles of calcium using its atomic weight. Then, use Avogadro's number (6.022 x 10^23 atoms per mole) to convert moles to atoms.
