Number of mole of sucrose "sa 0.005
Number of mole of urea = Ss =0.03
Number of mole of H20 = =O =5.5
Mole fraction of solvent sine sucrose and urea are non — volatile
Xe = 5.5 = 5.5
A 5.5 +0.005 +0.03 5.535
Xa = 0.99
P= PP Axx,
P =23.756 x 0.99 Torr
P=23.52

For trianglea = 15 cm b = 14 cm c = 13 cm
Let the height of the parallelogram be h cm. Then, area of the parallelogram= Base x Height = 15 x h = 15h cm2 According to the question,Area of the parallelogram                   = Area of the triangle
Hence, the height of the parallelogram is 5.6 cm.
