How many atoms are on one mole of MgCI?

Answer 1

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.

Answer 2

The same number of atoms that are in one mole of anything. Avogadro's number, 6.022 X 1023. No units as this number is the same as saying ' one dozen ', or ' one gross. '

Answer 3

6.023*10^23 atoms (Avagadro's number)

Answer 4

6.02*10^23 atoms (avogadros constant)
