Statement-1 : Molality of pure ethanol is lesser than pure water
Statement-2 : As density of ethanol is lesser than density of water
[Given : `d_("ethanol") = 0.789 gm//ml, d_("water") = 1gm//ml`]

Options

A. Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.
B. Statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1.
C. Statement-1 is false, statemetn-2 is true
D. Statement-1 is true, statement-2 is false.

Explanation

Molarity of pure ethanol `(1)/((46)/(1000))=(1000)/(46)`
Molarity of pure water `(1)/((18)/(1000))=(1000)/(18)`
`m_(C_(2)H_(5)OH)ltm_(H_(2)O)`
density is not used to calculate molarity.
