The table below shows how much of the mass of the Sun and theEarth are made up of each element (by mass). Note that, for thisproblem, the amounts have been randomized somewhat from their realvalues. For your answers to this problem, use the values given inthe table below. Note that because of rounding, uncertainties inthe known values, the applied randomization, and small differencesbetween the solar nebula composition and the composition of theSun, it is possible to have answers more than 100%.
| Element | Percentage by Mass in the Sun | Percentage by Mass in the Earth |
| Hydrogen | 71.1% | 0.0033% |
| Helium | 27.4% | 2 × 10−8% |
| Carbon | 0.25% | 0.045% |
| Nitrogen | 0.08% | 0.0004% |
| Oxygen | 0.65% | 30.4% |
| Neon | 0.12% | 4 × 10−10% |
| Magnesium | 0.07% | 13.9% |
| Silicon | 0.06% | 16.7% |
| Sulfur | 0.04% | 2.9% |
| Iron | 0.14% | 32% |
Assume that all of the iron in the solar nebula in the Earth'svicinity was incorporated into the Earth. Use the data in the tableto calculate what percentages of the available silicon, sulfur, andoxygen were incorporated.
The percentage of silicon is  %.
The percentage of oxygen is  %.
The percentage of sulfur is  %.
