A molecule of water has a mass of 18 amu.
A water molecule spends the most time in the ocean reservoir, as oceans hold the largest volume of water on Earth.
The glucose molecule is much larger than the water molecule.
The Pacific Ocean is salty, there is no fresh water in it.
fresh water doesnt have saltinity in it but, ocean water does.
Residence time of water molecule in the ocean is estimated to be 3000 years. This answer is wrong because this question was asked in exam for the post of junior engineer and the options were- a) 3.5 year b) 3.5 million years c) 35 years d) 35000 years So answer is one from the above..

One.
The water molecule could evaporate due to heat from the sun, forming a water vapor cloud. This cloud could then be carried by the wind towards the ocean. Upon reaching a colder environment over the ocean, the vapor would condense back into liquid form and eventually fall as precipitation into the ocean.

Only about 10 of the water that evaporates from a salty ocean is fresh water.
