The volume occupied by 0.2 mole of methane at N.T.P. is

Calculate the pH of 0.5L of a 0.2 M NH_(4)Cl-0.2 M NH_(3) buffer before and after addition of (a) 0.05 mole of NaOH and (b) 0.05 mole of HCl . Assume that the volume remains constant.[Given: pK_(a) of NH_(3)=4.74]

Calculate the value of proportionality constant k for 1 mole of a gas which occupies 22.4L of volume under the given conditions of temperature and pressure.

By Avogadro's law, V=kn If volume occupied by 1 mole of a gas at STP is 22.4 L, then what will be the value of k if we take 0.5 mole of gas under same condition of temperature and pressure
