To determine the number of atoms in one mole of MgCl2 (magnesium chloride), you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms/molecules per mole.
First, you need to calculate the molar mass of MgCl2.
Magnesium (Mg) has an Atomic Mass of approximately 24.31 g/mol.
Chlorine (Cl) has an atomic mass of approximately 35.45 g/mol (rounded to two decimal places).
Now, add the atomic masses of one magnesium atom and two chlorine atoms to find the molar mass of MgCl2:
MgCl2 molar mass = (1 x Mg atomic mass) + (2 x Cl atomic mass)
MgCl2 molar mass = (1 x 24.31 g/mol) + (2 x 35.45 g/mol)
MgCl2 molar mass = 24.31 g/mol + 70.90 g/mol
MgCl2 molar mass = 95.21 g/mol
So, the molar mass of MgCl2 is approximately 95.21 g/mol.
Now, using Avogadro's number, you can calculate the number of atoms in one mole of MgCl2:
Number of atoms in 1 mole of MgCl2 = 6.022 x 10^23 atoms/molecules per mole
Now, divide this by the molar mass of MgCl2 (95.21 g/mol):
Number of atoms in 1 mole of MgCl2 = (6.022 x 10^23 atoms/mol) / (95.21 g/mol)
Number of atoms in 1 mole of MgCl2 ≈ 6.32 x 10^21 atoms
So, there are approximately 6.32 x 10^21 atoms in one mole of MgCl2.
