Match the following physical quantities with units.

Explanation

A. Molarity=concentration in` "mol"L^(-1)`
Molarity`=("Number of moles")/("volume in litres")`
B. Mole fraction=Unitless
C. Mole`=("mass"(g))/("molar mass"(g"mol"^(-1)))="mol"`
D. Molality =concentration in mol per kg solvent
Molality `=("Number of moles")/("Mass of solvent"(kg))`
E. The Si unit for pressure is the pascal (Pa). equal to one newton per square metre. `(N//m^(2)` "or" kg m^(-1)s^(-2))` this special name for the unit was added in 1971. before that. pressure in SI was expressed simply as `N//m^(2)`.
F. Unit of luminous intensity=candela.
The candela is the tuminous intensity. In a given direction of a source that emits monochromatic radiation of frequency `540xx10^(12)` hertz and taht has a radiant intensity in that direction of 1/683 wait per steradian.
G. Densty `=(" mass")/("volume")=g mL^(-1)`
H. Unit of mass=kilogram
The kilogram is the unit of mass. it is equal to the mass of the international prototype of the kilogram.
