JEE Main 2022 Chemistry question
2.5 g of protein containing only glycine is dissolved in water to make 500 mL of solution. The osmotic pressure of this solution at 300 K is found to be bar. The total number of glycine units present in the protein is . (Given : R = 0.083 L bar )
Answer: 330
Solution
= CRT gives = (2.5/M)(1000/500) , so M = 24751.5
