How many atoms are in 1.2g of sulfur?

Answer 1

Ar of S = 32.1g/mol

Number of moles = 1.2g / 32.1g/mol = 0.0374mol

One mole of a substance has the same number of particles as the Avogadro constant, which 6.02 x 10^23

Therefore, number of atoms = 0.0374 x 6.02 x 10^23 = 2.250 x 10^22 atoms

Answer 2

To find the number of atoms in 1.2g of sulfur, you would first convert the mass to moles using the molar mass of sulfur (32.06 g/mol). Then, you would use Avogadro's number (6.022 x 10^23) to calculate the number of atoms. Calculating it out, there are approximately 2.38 x 10^22 atoms in 1.2g of sulfur.
