The molecular weight of hemoglobin can be calculated using osmotic pressure
Osmotic pressure is a colligative property and it depends on molarity as
πV = nRT
where
π = osmotic pressure
V = volume = 1mL = 0.001 L
n = moles
R = gas constant = 0.0821 L atm / mol K
T = temperature = 25°C = 25 + 273 K = 298 K
Putting values we will get value of moles
![moles=\frac{\pi V}{RT}=\frac{0.00195X0.001}{0.0821X298}mol](https://tex.z-dn.net/?f=moles%3D%5Cfrac%7B%5Cpi%20V%7D%7BRT%7D%3D%5Cfrac%7B0.00195X0.001%7D%7B0.0821X298%7Dmol)
we know that
![moles=\frac{mass}{molarmass}](https://tex.z-dn.net/?f=moles%3D%5Cfrac%7Bmass%7D%7Bmolarmass%7D)
Therefore
![molarmass=\frac{mass}{moles}=\frac{5.10X10^{-3}g}{7.97X10^{-8}}=6.399X10^{4}g](https://tex.z-dn.net/?f=molarmass%3D%5Cfrac%7Bmass%7D%7Bmoles%7D%3D%5Cfrac%7B5.10X10%5E%7B-3%7Dg%7D%7B7.97X10%5E%7B-8%7D%7D%3D6.399X10%5E%7B4%7Dg)
Moles of Li2CO3 = 1.53/73.891 = 0.0207 mole
Since HCl is in excess, amount of CO2 will depend on the limiting reagent which is Li2CO3.
∴Moles of CO2 = Moles of Li2CO3 = 0.0207.
