how many atoms are in 10.0 grams of sulfur?
Well, sulfur has a molar mass of approximately 32.06 grams/mol. So if you have 10.0 grams of sulfur, you would have approximately 0.312 moles of sulfur. And since one mole of any substance contains approximately 6.022 x 10^23 atoms, you can multiply the moles by Avogadro's number to get the number of atoms. So, in this case, you would have approximately 1.88 x 10^23 atoms of sulfur. That's a whole lot of sulfur atom party going on!
To determine the number of atoms in a given amount of substance, you can use Avogadro's number and the molar mass of the substance.
1. Determine the molar mass of sulfur (S). The atomic mass of sulfur is approximately 32.06 g/mol.
2. Calculate the number of moles of sulfur using the given mass (10.0 grams) and the molar mass of sulfur:
Number of moles = Mass / Molar mass
Number of moles = 10.0 g / 32.06 g/mol
Number of moles ≈ 0.3123 mol
3. Use Avogadro's number, which represents the number of atoms in one mole of a substance:
Avogadro's number = 6.022 × 10^23 atoms/mol
4. Calculate the number of atoms in 0.3123 moles of sulfur:
Number of atoms = Number of moles × Avogadro's number
Number of atoms = 0.3123 mol × 6.022 × 10^23 atoms/mol
Number of atoms ≈ 1.88 × 10^23 atoms
Therefore, there are approximately 1.88 × 10^23 atoms in 10.0 grams of sulfur.
To determine the number of atoms in 10.0 grams of sulfur, you need to follow a series of steps. Here's how:
1. Determine the molar mass of sulfur (S). You can find this information on the periodic table. The molar mass of sulfur is approximately 32.06 grams/mole.
2. Use the molar mass to calculate the number of moles of sulfur in 10.0 grams of sulfur. To do this, divide the given mass (10.0 g) by the molar mass of sulfur:
Number of moles = Mass (g) / Molar mass (g/mol)
Number of moles = 10.0 g / 32.06 g/mol
Number of moles ≈ 0.312 moles
3. Apply Avogadro's number, which is approximately 6.022 x 10^23 atoms/mole. Multiply the number of moles of sulfur by Avogadro's number to find the number of atoms:
Number of atoms = Number of moles × Avogadro's number
Number of atoms = 0.312 moles × 6.022 x 10^23 atoms/mole
Number of atoms ≈ 1.88 x 10^23 atoms
Therefore, there are approximately 1.88 x 10^23 atoms in 10.0 grams of sulfur.
the molar mass of sulfur is 32.1 g
there are 6.02E23 atoms in a mole of sulfur
