1.	56 g of nitrogen and 96 g of oxygen are mixed isothermally at a total pressure of 10 atm. The partial pressures of oxygen and nitrogen (in atm) are respectively:
Answer» 4, 6 5, 5 2, 8 8, 2 Solution :`n_(N_(2)) = (56)/(28) = 2 , n_(O_(2)) = (96)/(32) = 3` `P_(N_(2)) = x_(N_(2)) xx P_("Total")` `= (2)/(2 + 3) xx 10 = 4 atm` `P_(O_(2)) = 10 - 4 = 6 atm`
