haemoglobin(MW=68000) contains 0.33%of gas to effuse through a porous plug and 100seconds for the same volumeof CH4 under the same condition the molecular weight of gas is

Answer 1

first calculate the 0.33%of hb you get amount of gas(MASS X ) present now use M1V1=M2V2 WHERE M1 =MASS X AND M2 =MASS OF CH4 IE 16 EQUATE THEM
