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 solution is 1.52 bar at the same temperature, what would be its concentration?

Answer:

Strength = 36 gL?1 Molarity =   We know that  = CRT ?. (i) Substituting the values in eqn. (i), 4.98      ?? (ii)   Also, 1.52 = C x R x 300   ?. (iii)    Dividing (iii) by (ii), or
