Question

hiw many moleluse of water are present in a drop of water which has a mass 50 mg​

Answer 1

Answer:

Using the formula Mass= Moles x Molecular Mass, we can find out the number of moles or particles in that particular drop of water.

The mass is given as 50 mg, so we convert mg to the SI unit of mass, and replace “mass” in the equation with whatever answer you get.

The Molecular Mass of Water is 18, as the relative atomic mass of Hydrogen is 1 (there are two hydrogen atoms), and the relative atomic mass of Oxygen is 16.

Using the given information, we can find out the number of moles by dividing the mass of the water drop with the Molecular mass of water.
