Mass of 1 atom of 12 C =( text Atomic mass of C / text Avogadro's number) =(12 g /6.022 × 1023) =1.9927 × 10-23 g

Q. Match the following physical quantities with their units and choose the correct codes from the options given below.

Column I(Physical quantity) Column II(Unit)

A Molarity 1 mol

B Mole fraction 2 Unitless

C Mole 3 $m o l L^{- 1}$

D Molality 4 $m o l k g^{- 1}$

$A - (3), B - (2), C - (1), D - (4)$

$A - (2), B - (1), C - (4), D - (3)$

$A - (3), B - (2), C - (1), D - (3)$

$A - (1), B - (2), C - (4), D - (3)$

Mass of $1$ atom of $^{12} C = \frac{Atomic mass of C}{Avogadro’s number}$
$= \frac{12 g}{6.022 \times 1 0 ^{23}}$
$= 1.9927 \times 1 0^{- 23} g$

Column I(Physical quantity)		Column II(Unit)
A	Molarity	1	mol
B	Mole fraction	2	Unitless
C	Mole	3	$m o l L^{- 1}$
D	Molality	4	$m o l k g^{- 1}$
