Reducing the pressure from 1.0 to 0.5 atm would change the number of molecules in one mole of ammonia to

What is the number of molecules in 1.5 moles of ammonia ?

What is the number of molecules present in 1-5 mole of ammonia (NH_(3)) ?

The Compressibility factor for one mole of a van der Waal's gas at '0^circ C' and '100 atm' pressure is found to be '0.5 .' Assuming that the volume of gas molecule is negligible, calculate the van der Waal's constant 'a'?

At 35^(@)C the vapour pressure of pure chloroform is 0.359 at atm and that of pure acetone is 0.453 atm. A solution containing 1 mole of chloroform and 4 mole of acetone has a vapour pressure of (in atm)
