ઈથેનોલ મોલ \( = \frac{{69}}{{46}},\) ઈથેનોલ મોલઅંશ \( = \,\,\,\frac{{\frac{{69}}{{46}}}}{{\frac{x}{{18}} + \frac{{69}}{{46}}}}\)
\(\therefore \,\,\,0.6\,\, = \,\frac{{\frac{{69}}{{46}}}}{{\frac{x}{{18}} + \frac{{69}}{{46}}}}\,\,\)
\(\therefore \frac{x}{{18}} + \frac{{69}}{{46}} = \frac{{69}}{{46 \times 0.6}}\,\,\)
\(\therefore \,\,\frac{x}{{18}} + 1.5 = 2.5\,\)
\(\,\,\therefore \,\,\,x = 18\)
