​

Answer 1

Explanation:

The current best estimate for Earth mass is M ⊕ = 5.9722×1024 kg, with a standard uncertainty of 6×1020 kg (relative uncertainty 10−4). ... The recommended value in 1976 was (5.9742±0.0036)×1024 kg. It is equivalent to an average density of 5515 kg.

Answer 2

Answer:

The current best estimate of Earth is 5.9722 × 10^24 kg with a uncertainty of 6 × 10^20 kg. It is equivalent to an average density of 5515 kg/m^-3.
