Q. Few quantities with their units are listed below. Mark the units which are not correctly matched
(i) Density: $kg\, m ^{-3}$
(ii) Velocity of light :$ m s^ {-1}$
(iii) Planck’s constant: $J^{-1} s^{-1}$
(iv) Acceleration: $m s^{-2}$
(v) Force: $kg m$

Some Basic Concepts of Chemistry

Solution:

Planck’s constant $= J \,s $
Force $= kg\, m s^2 $
