Question

› Venus has a mass of approximately 4.9 * 10 ^ 24 kg. The approximate mass of Mercury is 3.3 * 10 ^ 23 kg.
Approximately how many kilograms greater is the mass of Venus than the mass of Mercury?
O 1.6 * 10 ^ 22 * kg
O 4.6 * 10 ^ 22 * k
O 1.6 * 10 ^ 24 * kg
O 4.6 * 10 ^ 24 * kG

Answer 1

Subtract the masses: 4.9×10^24 − 3.3×10^23 = 4.9×10^24 − 0.33×10^24 = 4.57×10^24 ≈ 4.6×10^24 kg.

Answer: 4.6 × 10^24 kg.
