Answer: 15 grams of magnesium will be present in the magnesium sulfate
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.
The balanced chemical reaction is:
[tex]Mg+H_2SO_4\rightarrow MgSO_4+H_2[/tex]
As the mass remains conserved at the end of the reaction, there will be 15 grams of Magnesium in magnesium sulphate.
