How many atoms of sulfur are in a 2.500 mole sample of pure sulfur? *
To find the number of atoms in a sample of sulfur, you can use Avogadro's number. Avogadro's number is a constant that represents the number of atoms in one mole of a substance. It is approximately 6.022 × 10^23 atoms/mol.
Step 1: Determine the number of moles of sulfur
You are given that the sample contains 2.500 moles of sulfur.
Step 2: Use Avogadro's number to find the number of atoms
Multiply the number of moles by Avogadro's number to find the number of atoms.
Number of atoms = Number of moles × Avogadro's number
Number of atoms = 2.500 mol × 6.022 × 10^23 atoms/mol
Calculating the number of atoms:
Number of atoms = 1.5055 × 10^24 atoms
Therefore, there are approximately 1.5055 × 10^24 atoms of sulfur in a 2.500 mole sample of pure sulfur.
To determine the number of atoms of sulfur in a mole sample, you can use Avogadro's number. Avogadro's number is defined as 6.022 x 10^23, which represents the number of particles (atoms, molecules, etc.) in one mole of a substance.
In this case, we have a 2.500 mole sample of pure sulfur. To find the number of atoms in the sample, we can multiply the number of moles by Avogadro's number:
Number of atoms = Number of moles x Avogadro's number
Number of atoms = 2.500 moles x (6.022 x 10^23 atoms/mole)
Calculating this gives us:
Number of atoms = 1.5055 x 10^24 atoms
Therefore, there are approximately 1.5055 x 10^24 atoms of sulfur in a 2.500 mole sample of pure sulfur.
