A homogeneous ideal gaseous reaction \( \mathrm{AB}_{2}(\mathrm{~g}) \rightleftharpoons \mathrm{A}(\mathrm{g})+2 \mathrm{~B}(\mathrm{~g}) \) is carried out in a 25 litre flask at \( 27^{\circ} \mathrm{C} \). The initial amount of \( \mathrm{AB}_{2} \) was 1 mole and the equilibrium pressure was \( 1.9 \mathrm{~atm} \). The value of \( \mathrm{K}_{P} \) is \( \mathrm{x} \times 10^{-2} \). The value of \( \mathrm{x} \) is _____________(Round off to nearest integer)\[
