Answer:
[tex]\%\ Composition\ of\ iron=69.92\ %[/tex]
[tex]\%\ Composition\ of\ oxygen=30.08\ \%[/tex]
Explanation:
Percent composition is percentage by the mass of element present in the compound.
Given , Mass of iron = 1.116 g
Mass of oxygen = 0.48 g
Total mass of the rock = 1.596 g
[tex]\%\ Composition\ of\ iron=\frac{Mass_{iron}}{Total\ mass}\times 100[/tex]
[tex]\%\ Composition\ of\ iron=\frac{1.116}{1.596}\times 100[/tex]
[tex]\%\ Composition\ of\ iron=\frac{111.6}{1.596}[/tex]
[tex]\%\ Composition\ of\ iron=69.92\ \%[/tex]
[tex]\%\ Composition\ of\ oxygen=\frac{Mass_{oxygen}}{Total\ mass}\times 100[/tex]
[tex]\%\ Composition\ of\ oxygen=\frac{0.48}{1.596}\times 100[/tex]
[tex]\%\ Composition\ of\ oxygen=\frac{48}{1.596}[/tex]
[tex]\%\ Composition\ of\ oxygen=30.08\ \%[/tex]
