Osmotic pressure is 0.0821 atm at temperature of 300K300K. Find concentration in mole/litre.

A

0.033

B

0.066

C

0.33×10−20.33 \times 10^{- 2}

D

3

Answer

0.33×10−20.33 \times 10^{- 2}

Explanation

Solution

π=CRT\pi = CRT, C=πRT=0.08210.821×300=0.33×10−2C = \frac{\pi}{RT} = \frac{0.0821}{0.821 \times 300} = 0.33 \times 10^{- 2}.
