Assume R=0.08206 L * atm/mol*K
Please help and offer some explanation if you can, I keep getting it wrong and every time I get it wrong I have to watch a 15 minute long video :(
Please help! Chemistry question!! What is the osmotic pressure in atm of a 0.50 M urea solution at 25 degrees Celsius?

✔ 最佳答案
For urea, van't Hoff index, i = 1Osmotic pressure
= iMRT
= 1 × (0.50 mol/L) × [0.08206 L atm / (mol K)] × [(273 + 25) K]
= 12.2 atm

Are you using Kelvin as the temperature?
