Which solution has the lower freezing point ? 10 g of methanol ( CH_3 OH_)in 100 g of water ( or ) 20 gof ethanol(CH_2 H_5OH)in 200 g of water

Which solution has the lower freezing point ? 10 g of methanol ( CH_3

1.	Which solution has the lower freezing point ? 10 g of methanol ( CH_3 OH_)in 100 g of water ( or ) 20 gof ethanol(CH_2 H_5OH)in 200 g of water
Answer» Solution :`Delta T _(f) = K _(f), m.i.e. Delta T_(f) prop m` `m_(CH_(3)-OH)= (((10)/(32)))/(0.1) = 3. 125m` `m _(C_(2)H_(5)-OH)= (((20)/(46)))/(0.2)= 2. 174 m` `therefore` Depression in freezing point is more in methanol solution and it will have lower freezing point.
