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.
