Solute A is absorbed from a gas into water in a packed bed operating at steady state. The absorber operating pressure and temperature are 1 atm and 300 K, respectively. At the gas-liquid interface y_i=1.5 x_i where y_i and x_i are the interfacial gas and liquid mole fractions of A, respectively. At a particular location in the absorber, the mole fractions of A in the bulk gas and in the bulk water are 0.02 and 0.002, respectively. If the ratio of the local individual mass transfer coefficients k_y/k_x=2 for the transport of A on the gas-side (k_y) to that on the water-side (k_x), then y_i equals ______ (rounded off to 3 decimal places).
