1 cc of CCl4 contains 1.59 g of it = (1.59/1.58) ∴ 12 L of liquid CCl4 will contain = 12 × 1000 × 0.0103 ⇒ 0.744× 1026 moles of it

Q. How many molecule are present in $12 L$ of liquid $CC l_{4}$ ? The density of the liquid is $1.59 g c m^{- 3}$ ?

$7.44 \times 1 0^{26}$

$0.744 \times 1 0^{26}$

$1.59 \times 1 0^{26}$

$15.9 \times 1 0^{26}$

$1 cc$ of $CC l_{4}$ contains $1.59 g$ of it $= \frac{1.59}{1.58}$
$∴ 12 L$ of liquid $CC l_{4}$ will contain
$= 12 \times 1000 \times 0.0103$
$\Rightarrow 0.744 \times 1 0^{26}$ moles of it
