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 answer to this is true.
Answer:
The correct formula is...
Nal
Answer:
123.0*12.35/(0.05*6.049)
first do in small bracket 123.0*12.35/0.30245
and then divide 123.0*40.83319557
and multiply 5022.483055
