calculate the mole fraction of benzene in solution containing 30 percent by mass in ccl4?

$\huge\color{red}{\textbf{\textsf{Answer⇨}}}$

Moles of Benzene = 30gm

Moles of ccl4 = 70gm

$moles \: of \: benzene \: = \frac{30}{78} \\ 0.385 \\ moles \: of \: ccl4 = \frac{70}{154} \\ 0.45 \\ moles \: fraction \: = \frac{0.385}{0.385 + 0.45} \\ 0.461$

Answer 2

Answer:

Moles of Benzene = 30gm

Moles of ccl4 = 70gm

\begin{gathered}moles \: of \: benzene \: = \frac{30}{78} \\ 0.385 \\ moles \: of \: ccl4 = \frac{70}{154} \\ 0.45 \\ moles \: fraction \: = \frac{0.385}{0.385 + 0.45} \\ 0.461\end{gathered}

molesofbenzene=

78

30

0.385

molesofccl4=

154

70

0.45

molesfraction=

0.385+0.45

0.385

0.461
