WebThe mole fraction of a gas is the number of moles of that gas divided by the total moles of gas in the mixture, and it is often abbreviated as x x: x_1=\text {mole fraction of gas 1}=\dfrac {\text {moles of gas 1}} {\text {total moles of gas}} x1 = mole fraction of gas 1 = total moles of gasmoles of gas 1 WebThe total inlet gas flow is 30 mol s-1 and the inlet water flow is 90 mol s-1 . The equilibrium relation for the acetone is y = 2.53 x (as shown in the plot below). Find the number of equilibrium stages required. Note that since the solute is dilute, we may use the approximation that mole fractions are approximately equal to mole ratios.
