The osmotic pressure of 0.200 g of haemoglobin in 20.0 ml of solution is 2.88 torr at 25^(@)C. Calculate the molecular weight of haemoglobin.

Answer»


Solution :`"Molar conc. of haemoglobin (C)"=(0.200)/(M)xx(1000)/(20)"mol L"^(-1)","pi=CRT`
`"i.e.,"(2.88)/(760)" atm"=((10)/(M)" mol L"^(-1))xx("0.082 L atm K"^(-1)"mol"^(-1))xx(298K)"or"M="64484 G mol"^(-1)`
