CONCLUSIONS: Suppose a student is given 5.375 g of a powdered mixture to
separate. Because the mixture contains iron shavings, he decides to separate
them using a magnet. He obtains 1.824 g of iron. What is the mass percent of
iron in the mixture?
33.93%

Respuesta :

Answer:

[tex]\%Fe=33.93\%[/tex]

Explanation:

Hello,

In this case, since the mass percent of iron is computed via the division of the mass of iron by the mass of the mixture including the 100 %:

[tex]\%Fe=\frac{m_{Fe}}{m_{mixture}}*100\%[/tex]

Considering the given data we obtain:

[tex]\%Fe=\frac{1.824g}{5.375g}*100\%\\ \\\%Fe=33.93\%[/tex]

Best regards.
