A flue gas flows at the rate of 10 k m o l / s 10 k

Question:

A flue gas flows at the rate of $10 k m o l / s$ at $298 K$ and $1 a t m$ with a ${S O}_{2}$ content of $0.15 m o l %$ . Ninety percent of the sulfur dioxide is to be removed by absorption with pure water at $298 K$ . The design water flow rate will be $50 %$ higher than the minimum. Under these conditions, the equilibrium line is (Benítez, 1993) $Y_{i} = 10 X_{i}$ , where $Y_{i} = m o l {S O}_{2} / m o l$ air and $X_{i} = m o l {S O}_{2} / m o l$ water.
