Question

There is an average of 3.5×10−2 kilograms of dissolved salt in each liter of seawater. The Pacific Ocean contains approximately ​ 6.6×1020 ​ liters of seawater.

Answer 1

Given that there is average 3.5*10^-2 kg salt in Each liter of seawater

The Pacific ocean contains 6.6*1020 liters of water

So,

    the total salt in the ocean would be 3.5*10^-2 * 6.6*1020

                                                               = 3.5*10^-2 * 6732

                                                               = 235.620

Ans: the Pacific ocean contains 235.620 KG of salt
