To find out how much greater the mass of Phobos is than the mass of Deimos, we can subtract the mass of Deimos from the mass of Phobos.
Mass of Phobos = \(10.8 \times 10^{15}\) kg
Mass of Deimos = \(2.0 \times 10^{15}\) kg
Now calculate the difference:
\[
\text{Difference} = \text{Mass of Phobos} - \text{Mass of Deimos}
\]
\[
\text{Difference} = (10.8 \times 10^{15}) - (2.0 \times 10^{15}) = (10.8 - 2.0) \times 10^{15}
\]
\[
\text{Difference} = 8.8 \times 10^{15} \text{ kg}
\]
Therefore, the mass of Phobos is greater than the mass of Deimos by \(8.8 \times 10^{15}\) kilograms.
The correct answer is **A) 8.8 * 10^15 kilograms**.
Mass of Phobos = \(10.8 \times 10^{15}\) kg
Mass of Deimos = \(2.0 \times 10^{15}\) kg
Now calculate the difference:
\[
\text{Difference} = \text{Mass of Phobos} - \text{Mass of Deimos}
\]
\[
\text{Difference} = (10.8 \times 10^{15}) - (2.0 \times 10^{15}) = (10.8 - 2.0) \times 10^{15}
\]
\[
\text{Difference} = 8.8 \times 10^{15} \text{ kg}
\]
Therefore, the mass of Phobos is greater than the mass of Deimos by \(8.8 \times 10^{15}\) kilograms.
The correct answer is **A) 8.8 * 10^15 kilograms**.
