At 300 ~K , 6 ~g of urea was dissolved in 500 mL of water. What is the osmotic pressure (in atm) of resultant solution? aligned & (R=0.082 ~L ~atm ~K ⁻¹ ~mol ⁻¹ ) & ( C =12 ; N =14 ; O=16 ; H =1) aligned
Options
- A0.492
- B2.46
- C4.92
- D49.2
Correct answer
C. 4.92
Step-by-step solution
Osmotic pressure ( )= CRT Given, Weight of urea =6 ~g Molecular weight of urea Number of mole of urea = Weight Molecular weight 6 60 =0.1 ~mole aligned & concentration ( C )= mole volume & & = 0.1 0.5 [1 ~L =10^3 ~mL ] aligned (C) =0.2 ~mole / liter . aligned & =0.2 0.082 300 & =4.92 ~atm aligned
