Question

What is mass of sucrose in 1l solution which is isotonic with 6.6g/l of urea solution

Answer 1

Answer:

isotonic means same concentration

here sucrose is isotonic to urea

here urea is 6.6g in 1l of solution

that is in term of molarity 0.11 moles in l l

as the surcose is isotonic with urea means the no.of moles in 1l solution is same

so,we can say that 0.11 moles of sucrose in 1l

moles=weight of sucrose taken/molecular weight

so weight taken=0.11*342

37.62g

hope so helpful

there is another method if needed ask in comment..
