The Avogadro number: 6,02214129(27)×1023.
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
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.
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).
Divide that number by Avogadro's number: 3.968x10(23) / 6.02x10(23) = 0.659mol Mg, which would be about 16g.
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.
To find the number of moles of atoms in 4.1 x 10^(-12) g of oxygen, you first convert the mass to moles by dividing by the molar mass of oxygen (16 g/mol). 4.1 x 10^(-12) g / 16 g/mol = 2.56 x 10^(-13) moles of oxygen atoms.
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.
