This table shows sizes of Earth's oceans. Based on this table and the makeup of Earth's total water, which reasonable conclusion can be made? A) Earth's seas contain more salt water than the oceans. Earth's land has more surface area than Earth's oceans. Earth's largest source of salt water is the Pacific Ocean. D) The Pacific Ocean is larger than all other oceans combined. USATestprep, LLC...

The answer would be

C) Earths largest source of salt water is the pacific ocean

It would be Earth's largest source of salt water is the Pacific Ocean.

Explanation:

D is false because if you add all the percentages of the other oceans up. it would be greater than the pacific ocean, so its wrong.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
