The number of grams in a mole of atoms depends on the element in question. A mole of any substance contains approximately (6.022 \times 10^{23}) entities, known as Avogadro's number. The mass in grams of one mole of atoms is equal to the Atomic Mass of the element, expressed in grams per mole (g/mol) on the Periodic Table. For example, one mole of carbon, with an atomic mass of about 12.01 g/mol, weighs approximately 12.01 grams.

How many atoms are there in 16.3 grams of sulfur?
There are about 6.02 x 10^23 atoms in 16.3 grams of sulfur, which is Avogadro's number representing one mole of atoms or molecules. This is known as a mole, where one mole of any element contains Avogadro's number of 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 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).
