Question

mass of the solution of 1 molal glucose solution to get 0.2 mole of glucose is

Answer 1

Answer:

236g

Explanation:

m = no of moles of solute/mass of solvent (inKg)

n = 0.2

0.2 = m(g)/180                          [Molar mass of glucose = 180g/mol]

m(g) = 36g = mass of glucose

m  = 0.2/k

1 = 0.2/k

k = 0.2Kg = 200g = mass of solvent

mass of solution = mass of solvent + mass of solute(glucose)

                           = 200+36 =236g
