Answer:

The value is [tex] M_{o} = 175 g[/tex]

Explanation:

Generally the reaction between oxygen and magnesium is

[tex]2Mg_{({s})} + O_2_{(g)} \to 2MgO_{(s)}[/tex]

Generally from the law of mass conservation in a chemical reaction we have that

[tex]M_{m} + M_{o} = M_{z}[/tex]

Here  [tex]M_{m}[/tex]  is the mass  of  magnesium

           [tex]M_{o}[/tex] is the mass  of oxygen

           [tex]M_{z}[/tex]  is the mass  of  magnesium oxide

So

      [tex]425+ M_{o} = 600[/tex]

=>     [tex] M_{o} = 600 - 425[/tex]

=>     [tex] M_{o} = 175 g[/tex]
