(a)
To Find: The number of moles of water in all the Earth’s oceans.
(a)
Answer to Problem 43P
Given:
Average depth,
Formula used:
The volume of the oceans:
Here,
Density of sea water is
Write the expression for the number of moles:
Here,
Calculation:
As compared to the Earth’s radius, the average depth is very small. So, the volume of the ocean is calculated as that of a spherical shell with surface area
The number of moles is calculated with the help of seawater density and molecular weight of water,
Conclusion:
The number of moles is
