Question

Mercury has a mass of 3.30 * 10 23 kg.

Mars has a mass of 6.42 x 10 23 kg.
How many times more massive is Mars than Mercury?
51x 10 23 kg
51
1.95 10 23 kg
1.95

Answer 1

Option (4)

Explanation:

Mass of Mercury = 3.3 ×
`10^(23)` kg

Mass of Mars = 6.42 ×
`10^(23)` kg

Therefore, ratio of the masses of Mars and Mercury =
`(6.42* 10^(23) )/(3.30* 10^(23))`

= 1.95

`\frac{\text{Mass of Mars}}{\text{Mass of mercury}}=1.95`

Mass of Mars = 1.95 × (Mass of Mercury)

Therefore, mass of Mars is .95 times more than Mercury.

Option (4) will be the answer.
