The osmotic pressure of a solution containing `0.1 mol` of solute per litre at `273 K` is

Options

A. `0.1/1 xx 0.082 xx "atm"`
B. `0.1 xx 2 xx 0.082 xx 273 "atm"`
C. `1/0.1 xx 0.082 xx 273 "atm"`
D. `0.1/1 xx 273/0.082 "atm"`

Answer

A

Explanation

`pi V = nRT,`
`pi xx 1 = 0.1 xx 0.082 xx 273`
`:. pi = (0.1 xx 0.082 xx 273)/1 "atm".`
