1.	28 g of each of the following gases are taken at 27^(@)Cand 600 mm pressures. Which of these will have the least volume?
Answer» <P>HBr HCl HF HI Solution :PV=NRT or `V=(nRT)/(P)`. As P and T are same for all given gases, `V prop n`. As `n=(w)/(M)`, n will be LEAST for which M is maximum viz. HI.
