1.	At 27^(@) C , a closed vessel contains a mixture of equal weights of helium (mol.wt = 4) , methane (mol.wt = 16) and sulphur dioxide (mol.wt = 64) . The pressure exerted by the mixture is 210 mm . If the partial pressures of helium , methane and sulphurdioxide are P_1 , P_2 and P_3 respectively , which one of the following is correct ?
Answer» `P_3gt P_2 GT P_1` `P_1gt P_2 gtP_3` `P_1 gt P_3gt P_2` `P_2gt P_3gt P_1` ANSWER :B
