A mixture contains two components A and B . The solubilities of A and B in water near its boiling point are 10 grams per 100 ml and 2 g per 100 ml respectively. How will you separate A and B from this mixture?

The solubility of 'CaF_2' in water at '298 K' is '1.7 xx 10^(-5)' grams per '100 cm^3 .' Calculąte the solubility product of 'CaF_2' at '298 K'.

Food X contains 6 units of vitamins A and 7 units of vitamins B per gram and it costs 12 paise per gram.Food Y contains 8 units of vitamin A and 12 units of vitamins B per gram and it costs 20 paise per gram.Daily minimum requiremrnts of vitamin A and vitamin B are 100 units and 120 units respectively.Formulate the LPP mathematically so that the cost is to be minimized.

The solutions A and B are 0.1 and 0.2 molar in a substance. If 100 ml of A is mixed with 25 ml of B, and there is no change in volume, then the final molarity is

A solution of ,urea In water boils at 100.18 ^@C .‘Calculate the freezing point of the same solution. Molar constants K_t and K_b are 1.86 and 0.512 km^-1 respectively. How-will you differentiate between molar elevation constant and molar depression constant ?
