Answer:
50 gram of MgS contains =21.56 gram of Mg
Explanation:
Molecular mass of MgS is 56.37 g/mol.
Atomic mass of 1 mole Mg is 24.305
Therefore 56.37 gram of MgS contains 24.305 gram of Mg
1 gram of MgS contains [tex]\frac{24.305}{56.37}[/tex] gram of Mg
50 gram of MgS contains [tex]\frac{24.305}{56.37}[/tex] ×50 gram of Mg
=21.56 gram of Mg
