1.	400cc of N_2 at 600mm and 500cc of O_2 at 300mm are quantitatively transferred in to an empty vessel of X 2 L capacity. Calculate the pressure of the mixture and partial pressures.
Answer» <P> Solution :PRESSURE of the final mixture `= P = (P_(1)V_(1) + P_(2)V_(2))/(V)` ` = (400 xx 600 + 500 xx 300)/(2000) = 195` mm PARTIAL presssure of nitrogen ` = (P_(1)V_(1))/(V) = (400 xx 600)/(2000) = 120` mm Partial pressure of oxygen ` = (P_(2)V_(2))/(V) = (500 xx 300)/(2000) = 75` mm
