Liquid ammonia ionises to a slight extent. Its self ionisation constant is `10^(-30) at - 50^(@) C ` , then the number of amide iona present per 1 cc of it at `-50^(@) ` C is
The ionisation constant of NH_3 is 1.77 xx 10^(-5) . What is the 'a' and 'pH' of 0.05M ammonia solution?
Calculate the number of molecules present in 1.12 xx 10^(-7) c.c. of a gas a STP.
A 1% (w/v) aqueous solution of potassium chloride has extent of ionisation 0.82 in water it 18^@C . Calculate the osmatic pressure.
Density of a liquid at 0^(@)C is 13.6 gm/c.c., and its coefficient of real expansion is 18xx10^(-5)//""^(@)C . If the temperature is increased to 200^(@)C , percentage change in its density is
An electric heater with constant heat supply rate is used to convert a certain amount of liquid ammonia to saturated vapour at high pressure. The heater takes 14 minutes to bring the liquid at 15^@C to the boiling point of 50^@C and 92 minutes to convert the liquid at the boiling point wholly to vapour. If the specific heat capacity of liquid ammonia is 4.9 kJ/kg K, the latent heat of vaporisation of ammonia in kJ/kg is
