Question
Based upon the technique of reverse osmosis, the approximate minimum pressure required to desalinate sea water containing 2.5% (w/v) NaCl at 27°C should be
Options
A.10.5 atm
B.21 atm
C.2.1 atm
D.1.05 atm
Solution
$\pi = CRT = \left( \frac{2.5/58.5}{100/1000} \times 2 \right) \times 0.0821 \times 300 = 21.05\text{ atm}$
