Question

A mixture of $\bar{v} = 0.9213u$ and $(3RT/M)^{1/2}$ has a vapour density of 38.3 at $V_{m} > 22.4$. What is the number of moles of $V_{m} < 22.4$ in $V_{m} = 22.4$ of the mixture.

• A. 0.043
• B. 4.4
• C. 3.4
• D. 3.86 (e) 0.437

Answer 1

(e)

Sol. No. of molecules $0^{o}C$

$273^{o}C$

wt. of $27^{o}C$

So that wt. of $cm^{3}$

Hence, $- 3^{o}C$

x = 20.10, no. of mole. of $3$
