Question

22.22 g of urea was dissolved in 300 grams
water. Calculate the number of moles of urea and
molality of the urea solution (molar mass of urea
is 60 g mol-)​

Answer 1

Answer:

mole = weight / molar mass

22.22/ 60 = 0.37

molality= mole × 1000 /weight of solvent

0.37× 1000/300 =3.7/3 =1.233m
