`100ml` of ethyl alcohol is made up to litre with water. Molality of this solution is (density of ethyl alcohol is `0.46(gm)/(ml)`)

Find density of ethyl alcohol

80g NaOH was added to 2L water. Find molality of solution density of water =1g//mL .

120g NaOH was added to 2L water. Find molality of solution density of water =1g//mL .

What will be the nature of the solution when ethyl alcohol and water are mixed ?

138 g of ethyl alcohol is mixed with 72 g of water. The ratio of mole fraction of alcohol to water is

46 gms of ethyl alcohol is dissolved in 18 gms of water. Calculate the mole fraction of ethyl alcohol. (At. wt of C = 12, 0 = 16, H= 1).

Mole fraction of ethyl alcohol in aqueous ethyl alcohol ( C_2H_5OH ) solution is 0.25. Hence percentage of ethyl alcohol by weight is:

Mole fraction of ethyl alcohol in aqueous ethyl alcohol ( C_2H_5OH ) solution is 0.15. Hence percentage of ethyl alcohol by weight is:

Mole fraction of ethyl alcohol in aqueous ethyl alcohol ( C_2H_5OH ) solution is 0.65. Hence percentage of ethyl alcohol by weight is:

Mole fraction of ethyl alcohol in aqueous ethyl alcohol ( C_2H_5OH ) solution is 0.50. Hence percentage of ethyl alcohol by weight is:
