Question

how mass of microscopic particles can be measured.?​

Answer 1

Answer:

Defining the microscopic scale

So, we can think of the microscopic scale as being from a millimetre (10-3 m) to a ten-millionth of a millimetre (10-10 m). Even within the microscopic scale, there are immense variations in the size of objects.

Scan under a microscope an area corresponding to not less than 10 µg of the powder. Count all the particles having a maximum dimension greater than the prescribed size limit. Particle size characterization.
