Parts per million

Text Solution

Verified by Experts

(i) Mass percentage (m/m): It is mass of the component per 100 gm of the solution.
Mass % of component = `("Mass of component in solution" xx 100)/("Total mass of solution")`
(ii) Volume percentage (V/V): It is the volume of the component per 100 parts of volume of the solution.
Volume% = `("Volume of component in solution" xx100)/("Total Volume of solution")`
(iii) Parts per million : It is the parts of a component per million parts of the solution.
ppm A = `("Mass of component A")/("Total Mass") xx 10^6`
(iv) Molarity (M)
Molarity `= ("No.of moles of solute")/("Volume of solution (in litre)")`
(v) Molality (m):
Molality(m) `= ("No. of moles of Solute")/("Mass of solvant (in kg.)")`
(vi) Normality:
`("No. of gram equivalent of solute")/( "Volume of solution in litre")`
(vii) Mole fraction :
`("No. of moles of component")/("Total moles of Solution")`
