The mass % of urea solution is 6 . The total weight of the solution is 1000 g . What is its concentration in mol L ⁻¹ ? (density of water =1.0 ~g ~mL ⁻¹ ) (C=12 u ; N=14 u ; O=16 u, H=1 u)

Options

  1. A1.5
  2. B1.064
  3. C1.12
  4. D0.80

Correct answer

B. 1.064

Step-by-step solution

aligned & Amount of urea =60 ~g & Moles of urea = 60 60 =1 ~mole & Molarity = Moles Volume of solution & = 1 Mole 1 Litre =1.0 M aligned
