At `300 K`, `36 g` of glucose present per litre in its solution has an osmotic pressure of `4.98 bar`. If the osmotic pressure of the solution is `1.5

Question

At 300K , 36g of glucose present per litre in its solution has an osmotic pressure of 4.98 ¯ . If the osmotic pressure of the solution is 1.52 ¯ at the same temperature, what would be its concentration? Select the correct answer from above options

Answer 1

Correct Answer - 0.061M First case W2=36g,P=4.98bar , Mw2( glucose )=180,V=1L, P= n V RT 4.98= 36 180×1 RT…..(i) Second case 1.52=CRT….(ii) Dividing Eq.(i) by Eq.(ii) , we get 4.98 1.52 = 0.2RT CRT C= 0.2×1.52 4.98 =0.61M The concentration of solution =0.061M
