Answer:

1.12 x 10²³atoms of F

Explanation:

Number of MgF₂ atoms = 5.6 x 10²² molecules;

 The unknown here is the number of Fluorine atoms found in the compound.

In MgF₂,

     1 mole of MgF₂ contains 2 moles of F;

From the given number of molecules we can also say that, MgF₂ contains 5.6 x 10²²atoms;

           1 mole of MgF₂ contains 2 moles of F;

    5.6 x 10²²atoms of MgF₂ will contain 2 x   5.6 x 10²² = 1.12 x 10²³atoms of F

The number of atoms of Flourine found in 5.6x10^/²² molecules of MgF2 is; 1.12 x 10²³atoms of F

Number of MgF₂ atoms as given = 5.6 x 10²² molecules;

We are required to determine the number of Fluorine atoms found in the compound.

In MgF₂,

  • 1 mole of MgF₂ contains 2 moles of F;

As given, MgF₂ contains 5.6 x 10²²atoms;

  • 1 mole of MgF₂ contains 2 moles of F;

Hence, 5.6 x 10²²atoms of MgF₂ will contain 2 x 5.6 x 10²² = 1.12 x 10²³atoms of Flourine.
