Question
One molecule of haemoglobin will combine with four molecules of oxygen. If 1.0 g of haemoglobin combines with 1.642 ml of oxygen at body temperature (270C) and a pressure of 760 torr, then what is the molar mass of haemoglobin?
Options
A.6,00,000
B.1,50,000
C.15,000
D.60,000
Solution
$\frac{1}{M} \times 4 = \frac{1 \times (1.642/1000)}{0.0821 \times 300} \Rightarrow M = 60000$
