\(x\) grams of water is mixed in \(69 \mathrm{~g}\) of ethanol. Mole fraction of ethanol in the resultant solution is 0.6 . What is the value of \(x\) in grams?
- A \(54\)
- B \(36\)
- C \(180\)
- D \(18\)
Answer & Solution
Correct Answer
(D) \(18\)
Step-by-step Solution
Detailed explanation
According to question, \[ \begin{aligned} & w_A=x \mathrm{~g}, m_A=18, X_A=1-0.6=0.4 \\ & w_B=69 \mathrm{~g}, m_B=46, X_B=0.4 \end{aligned} \] We know that, \[ X_A=\frac{n_A}{n_A+n_B} \]…
