To find the number of atoms in 16 g of oxygen (O), we first determine the number of moles: 16 g of O divided by its molar mass (approximately 16 g/mol) gives 1 mole of O, which contains about 6.022 x 10²³ atoms. For 8 g of sulfur (S), the molar mass is approximately 32 g/mol, so 8 g corresponds to 0.25 moles, equating to about 1.505 x 10²³ atoms of S. In total, there are approximately 7.527 x 10²³ atoms from both elements combined.
The Avogadro number: 6,02214129(27)×1023.
In 16g of O, there are approximately 3.02 x 10^23 atoms, as the atomic mass of oxygen is 16 g/mol. In 8g of S, there are approximately 6.02 x 10^23 atoms, as the atomic mass of sulfur is 32 g/mol.
Divide that number by Avogadro's number: 3.968x10(23) / 6.02x10(23) = 0.659mol Mg, which would be about 16g.
To find the number of atoms in 16g of oxygen (O) and 8g of sulfur (S), we first calculate the number of moles for each element. Oxygen has a molar mass of about 16 g/mol, so 16g of O corresponds to 1 mole (6.02 x 10²³ atoms). Sulfur has a molar mass of about 32 g/mol, so 8g of S corresponds to 0.25 moles (1.51 x 10²³ atoms). Therefore, the total number of atoms is 1.76 x 10²³ (1 mole of O + 0.25 moles of S).

The Avogadro number: 6,02214129(27)×1023.
One mole of oxygen has a mass of 16 grams and contains 6.022 x 10^23 oxygen atoms. Therefore, 16 grams of oxygen will also contain 6.022 x 10^23 oxygen atoms.
In 16g of O, there are approximately 3.02 x 10^23 atoms, as the atomic mass of oxygen is 16 g/mol. In 8g of S, there are approximately 6.02 x 10^23 atoms, as the atomic mass of sulfur is 32 g/mol.
1mol O = 16.0g (rounded to 1 decimal place) 1mol O atoms = 6.022 x 1023 atoms 16g O x 1mol/16g = 1mol O 1mol O x 6.022 x 1023atoms/mol = 6.022 x 1023 atoms O
Divide that number by Avogadro's number: 3.968x10(23) / 6.02x10(23) = 0.659mol Mg, which would be about 16g.
To find the number of atoms in 16g of oxygen (O) and 8g of sulfur (S), we first calculate the number of moles for each element. Oxygen has a molar mass of about 16 g/mol, so 16g of O corresponds to 1 mole (6.02 x 10²³ atoms). Sulfur has a molar mass of about 32 g/mol, so 8g of S corresponds to 0.25 moles (1.51 x 10²³ atoms). Therefore, the total number of atoms is 1.76 x 10²³ (1 mole of O + 0.25 moles of S).
That is 3.2 teaspoons.
To calculate the number of atoms present in a given mass of a substance, we need to use the concept of molar mass and Avogadro's number. The molar mass of oxygen (O) is approximately 16 g/mol, and the molar mass of sulfur (S) is approximately 32 g/mol. For oxygen: 16g / 16 g/mol = 1 mol of O. 1 mol of O contains 6.022 x 10^23 atoms (Avogadro's number). Therefore, 16g of O contains 6.022 x 10^23 atoms. For sulfur: 8g / 32 g/mol = 0.25 mol of S. 0.25 mol of S contains 0.25 x 6.022 x 10^23 atoms = 1.5055 x 10^23 atoms. Therefore, there are approximately 6.022 x 10^23 atoms in 16g of oxygen and approximately 1.5055 x 10^23 atoms in 8g of sulfur.
