Q. The average molar mass of chlorine is $35.5 g m o l^{- 1}$ . The ratio of $^{35} Cl$ to $^{37} Cl$ in naturally occurring chlorine is close to :

$4 : 1$

$1 : 1$

$2 : 1$

$3 : 1$

Av. molar mass $= \frac{n _{1} M _{1} + n _{2} M _{2}}{( n _{1} + n _{2} )}$

$35.5 = \frac{x \times 35 + 1 \times 37}{x + 1}$

$x = 3$

Q. The average molar mass of chlorine is 35.5gmol−1. The ratio of 35Cl to 37Cl in naturally occurring chlorine is close to :

4:1

1:1

2:1

3:1
