Find density of ethyl alcohol

If 40 g of ethyl alcohol is dissolved in 50 mL of water, then calculate the weight/volume percentage of ethyl alcohol present in the solution. (density of ethyl alcohol = 0.8 g/mL)

The vapour density of ethyl alcohol vapour is

The vapour density of ethyl alcohol vapour is

100 ml of ethyl alcohol is made upto a litre with distilled water. If the density of the ethyl alcohol is 0.46g/ml. What is the molality of the solution ?

Mole fraction of ethyl alcohol in aqueous ethyl alcohol 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 0.35. 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 0.28. Hence percentage of ethyl alcohol by weight is:

Mole fraction of ethyl alcohol in aqueous ethyl alcohol ( C_2H_5OH ) solution is 0.20. Hence percentage of ethyl alcohol by weight is:

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