For a fixed amount of a real gas when a graph of Z us P was plotted then at very high pressure slope was observed to be `0.01 atm^(-1)`. At the same temperature if a graph is plotted between PV us P then for 2 moles of the gas the y intercept is found to be 40 atm-litre. Calculate excluded volume in litres for 20 moles of the real gas/
