Question

The amoont of glucose to be dissolved in 500 g of water to produce a same loweing vapour pressite as 0.2 molal aqueous urea solution

Answer 1

This means that 0.2 moles of urea is present in 1000 g of the water. 180 grams of glucose to be dissolved in 500g of water so as to produce the same lowering in vapour pressure as that of 0.2 molal aqueous urea solution.
