The mass of glucose that should be dissolved in 50 ~g of water in order to produce the same lowering of vapour pressure as is produced by dissolving lg of urea in the same quantity of water is

Step-by-step solution

Lowering in vapour pressure is directly proportional to moles of solute particles aligned ( p)_ glucose &=( p)_ urea ( _ B )_ glucose &= ( _ B )_ urea W_ B 50 18 180 &= 1 18 50 60 W_ B &=3 ~g aligned
