  Match the following physical quantities with units :

Physical quantity	Unit
(i) Molarity	(a) \[g\,m{{L}^{-1}}\]
(ii) Mole fraction	(b) mol
(iii) Mole	(c) pascal
(iv) Molality	(d) Unitless
(v) Pressure	(e) mol \[{{L}^{-1}}\]
(vi) Luminous intensity	(f) candela
(vii) Density	(g) mol \[k{{g}^{-1}}\]
(viii)Mass	(h) \[N\,\,{{m}^{-1}}\]
	(i) kg

               

Answer:

  (i)  ? (e) Unit of molarity = mol \[{{L}^{-1}}\] (ii) ? (d) Mole fraction is unitless quantity (iii) ? (b) Unit of mole = mol (iv) ? (g) Unit of molality = mol \[k{{g}^{-1}}\] (v) ? (c) Unit of pressure = pascal (vi) ? (f) Unit of luminous intensity = candela (vii) ? (a) Unit of density = g \[m{{L}^{-1}}\] (viii) ? (i) Unit of mass = kg
