To calculate the number of moles from the number of atoms, we need to divide the number of atoms by Avogadro's number (6.022 × 10^23), which gives 3.59 moles of iron atoms.
To calculate the number of atoms in a sample of nitrogen or oxygen, you first need to know the amount of substance in moles (given in the question or calculated from the sample's mass and the molar mass of the element). Then, you can use Avogadro's number (6.022 x 10^23) to convert moles into the number of atoms. This value represents the number of atoms in one mole of a substance.
To calculate the number of carbon atoms in 2.50 grams of theobromine (C7H8N4O2), you first need to find the molar mass of theobromine. The molar mass of theobromine is 180.16 g/mol. From the molecular formula, there are 7 carbon atoms in one molecule of theobromine. Therefore, using the molar mass and the number of carbon atoms in the molecule, you can calculate the number of carbon atoms in 2.50 grams.
To determine the number of grams atoms of sulfur in a given mass of sulfur (g), you need to calculate the number of moles of sulfur first. Then, you can use Avogadro's number to convert moles to atoms. Finally, multiply the number of moles by Avogadro's number to find the number of atoms.
As in number? No of atoms = avagadros number (6.02X10^23) times number of mole of atoms
To calculate the number of moles from the number of atoms, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Divide the number of atoms by Avogadro's number to find the number of moles.
The number of reactants atoms must be equal to the number of products atoms.
Heptane has a chemical formula of C7H16. To calculate the number of atoms in heptane, add the number of carbon atoms (7) to the number of hydrogen atoms (16), resulting in a total of 23 atoms in heptane.
Sodium - 6 phosphorus - 2 oxygen - 8
The balanced chemical equation for the reaction is 2Na3PO4 + 3CaSO4 ----> Ca3(PO4)2 + 3Na2SO4.
To calculate the number of moles from the number of atoms, we need to divide the number of atoms by Avogadro's number (6.022 × 10^23), which gives 3.59 moles of iron atoms.
To calculate the number of oxygen atoms in 2 NO3 molecules, you first need to determine the total number of oxygen atoms in one molecule of NO3, which is 3 oxygen atoms. Since you have 2 NO3 molecules, you would multiply the number of oxygen atoms in one molecule by the number of molecules, giving you a total of 6 oxygen atoms.
To calculate the number of atoms in 13.2 mol of copper, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Multiply 13.2 mol by Avogadro's number to get the number of atoms: 13.2 mol * (6.022 x 10^23 atoms/mol) = 7.93 x 10^24 atoms. Therefore, there are approximately 7.93 x 10^24 atoms in 13.2 mol of copper.
To calculate the number of atoms in a sample of nitrogen or oxygen, you first need to know the amount of substance in moles (given in the question or calculated from the sample's mass and the molar mass of the element). Then, you can use Avogadro's number (6.022 x 10^23) to convert moles into the number of atoms. This value represents the number of atoms in one mole of a substance.
The effective atomic number for metallocenes can be calculated by considering the average atomic number of the metal atoms in the molecule and the number of metal atoms present. You can sum the product of the atomic number and the quantity of each metal atom in the molecule, and then divide by the total number of metal atoms to get the effective atomic number.
To calculate the number of carbon atoms in 2.50 grams of theobromine (C7H8N4O2), you first need to find the molar mass of theobromine. The molar mass of theobromine is 180.16 g/mol. From the molecular formula, there are 7 carbon atoms in one molecule of theobromine. Therefore, using the molar mass and the number of carbon atoms in the molecule, you can calculate the number of carbon atoms in 2.50 grams.
