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.

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.
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 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 much tin (Sn) is in 1462 atoms of tin?
To find the total amount of tin (Sn) in 1462 atoms, you would need to multiply the number of atoms by the atomic mass of tin (Sn), which is approximately 118.71 grams per mole. However, you also need to divide by Avogadro's number (6.022 x 10^23 atoms per mole) to convert from atoms to grams.
How many atoms are there in 0.575 grams cesium?
To find the number of atoms in 0.575 grams of cesium, you first need to convert grams to moles using the molar mass of cesium. Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in one mole of cesium. Multiply the number of moles by Avogadro's number to find the number of atoms in 0.575 grams of cesium.
How many atoms does 100 grams of gold have?
To find the number of atoms in 100 grams of gold, you would first calculate the number of moles using the molar mass of gold (197 grams/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. So, approximately 3.01 x 10^23 atoms of gold are present in 100 grams.

How many hydrogen atoms are in 5.839 grams of c8h8?
To find the number of hydrogen atoms in 5.839 grams of C8H8, first calculate the molar mass of C8H8, which is 104 g/mol. Next, find the number of moles of C8H8 in 5.839 grams using the molar mass. Since there are 8 hydrogen atoms per molecule of C8H8, multiply the number of moles by 8 to get the number of hydrogen atoms.
What is the mass of 19 atoms of copper in grams?
To calculate the mass of 19 atoms of copper in grams, you need to determine the molar mass of copper. The molar mass of copper is approximately 63.55 grams per mole. Then, you can use Avogadro's number (6.022 x 10^23 atoms per mole) to convert atoms to grams. So, the mass of 19 atoms of copper would be 19*(63.55/6.022e23) grams.
How many atoms are in 175 grams of calcium?
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.
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?
