Use scientific notation to estimate the mass of the planet's water. In your final answer, include all of your estimates and calculations.

Answer 1

• 1.94972 × 10¹⁹ kg

Explanation:

Mass of the planet:

• 4.8743 × 10²² kg

The water's mass:

• 4×10⁺²%

Mass of the planet's water:

• 4.8743 × 10²² * 4×10⁺² / 100 =
• 19.4972 × 10²²⁺²⁺² =
• 19.4972 × 10¹⁸ =
• 1.94972 × 10¹⁹
