How much of the Earth's mass is water?

Question

No details, just a question.

Answer 1

Not enough to subdue the magma.

Answer 2

2/3s

Answer 3

The Earth, a "water planet", contains some 0.07% water by mass or 0.4% by volume.

Answer 4

There is approximately 1.46 X 10^18 kilograms of water. That amount sounds larger if you say it as 1.46 million trillion kilograms.

That is 0.00002444% of the Earth's mass. Another way of expressing it is 2.444 ten millionths of Earth's mass.
