Match the following physical quantities with units.

<p>This is a Matching Type Questions as classified in NCERT Exemplar</p><p> (i) → (e) (ii) → (d) (iii) → (b) (iv) → (g) (v) → (c), (h) (vi) → (f) (vii) → (a) (viii) → (i)</p><p>Explanation:</p><p><strong> (i)</strong> It is defined as the number of moles of solute dissolved in 1 litre of solution. So, the unit of molarity is mol L-1<br><strong> (ii)</strong> Mole fraction is defined as the number of moles of a constituent divided by the total number of moles. So, it is unitless.</p><p><strong> (iii)</strong> Mole is the unit to measure the amount of an atom or molecule in SI system. it is symbolized as "mol".</p><p><strong> (iv) </strong>It is defined as the number of moles of solute dissolved in 1 kg of solvent, so, the unit of morality is mol kg-1.</p><p><strong> (v)</strong> It is defined as the force per unit area. so, the unit of pressure is Pascal.</p><p><strong> (vi) </strong>It is the amount of visible light released per unit solid angle in unit time. so, it's unit will be Candela.</p><p><strong> (vii) </strong>It is defined as the mass of a substance (in kg) divided by the volume of that substance (in mL). The unit of density is g ml-1</p><p><strong> (viii)</strong> Mass is used to measure the amount of a substance or an object. The unit of mass is kg.</p>
