The correct equation for one mole of a real gas is $a, b$ are constants)
$A$ and $B$ are ideal gases. At $T(\mathrm{~K}), 2 \mathrm{~L}$ of ' $A^{\prime}$ 'with a pressure of 1 bar is mixed with 4 L of ' $B$ ' with a pressure $p_B$ bar in a 100 L flash. The pressure exerted by gaseous mixture is 0.1 bar. What is the value of $p_B$ in bar?
