319213 \(\;138{\rm{g}}\) ethyl alcohol is mixed with \(72\;{\rm{g}}\) of water. The ratio of mole fraction of alcohol to water is

1 \(3: 4\)
2 \(1: 2\)
3 \(1: 4\)
4 \(1: 1\)
CHXII02:SOLUTIONS

319214 Assertion :
\(1.575 \mathrm{~g} \mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4} \cdot 2 \mathrm{H}_{2} \mathrm{O}\) in \(250 \mathrm{~mL}\) solution makes it \(0.1 \mathrm{~N}\).
Reason :
\(\mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4} \cdot 2 \mathrm{H}_{2} \mathrm{O}\) is a dihydrate organic acid.

1 If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
2 If both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
3 If Assertion is true but Reason is false.
4 Both Assertion and Reason are false
