Answer:

Percentage = 35%

Step-by-step explanation:

Given the following data;

Mass of iron, I = 2.090 x 10^24 kg

Mass of Earth, E = 5.972 x 10^24 kg

To find the percentage mass of iron on Earth;

[tex] Percentage = \frac {I}{E} * 100 [/tex]

Substituting into the formula, we have;

[tex] Percentage = \frac {2.090 * 10^{24}}{5.972 * 10^{24}} * 100 [/tex]

[tex] Percentage = 0.350 * 100 [/tex]

Percentage = 35%
