Question

Accepted Answer

Preparation of solutions like Normal, Molar, ppm, ppb, etc.

Normal solutions are prepared by dissolving a known weight of solute in a known volume of solvent.
Molar solutions are prepared by dissolving a known number of moles of solute in a known volume of solvent.
ppm (parts per million) solutions are prepared by dissolving a known weight of solute in a known volume of solvent and expressing the concentration in parts per million.
ppb (parts per billion) solutions are prepared by dissolving a known weight of solute in a known volume of solvent and expressing the concentration in parts per billion.

Accepted Answer

1)Gram equivalent weight per liter solution
