Problem

One litre vessel having 20 g charcoal (density 2.0 g/cm32.0 \text{ g}/\text{cm}^3 ) was filled with a gas at 300 K. The pressure of a gas was 760 torr. Due to adsorption the pressure of gas falls to 608 torr. What is the no. of gas molecule adsorbed per g of charcoal? (1) 2.4×10212.4 \times 10^{21} (2) 2.4×10202.4 \times 10^{20} (3) 2.4×10222.4 \times 10^{22} (4) 2.4×10232.4 \times 10^{23}
