Question

How many grams of oxygen are needed to

Answer 1

Answer:

The value is $M_{o} = 175 g$

Explanation:

Generally the reaction between oxygen and magnesium is

$2Mg_{({s})} + O_2_{(g)} \to 2MgO_{(s)}$

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

$M_{m} + M_{o} = M_{z}$

Here  $M_{m}$  is the mass  of  magnesium

           $M_{o}$ is the mass  of oxygen

           $M_{z}$  is the mass  of  magnesium oxide

So

      $425+ M_{o} = 600$

=>     $M_{o} = 600 - 425$

=>     $M_{o} = 175 g$
