How many millimoles of H2 S is dissolved when it is passed through 1

1.	How many millimoles of H2 S is dissolved when it is passed through 1 litre of water at 300 Ktemperature ? (value of KH = 5.6 ´ 104 bar and partial pressure is 3 ´ 108 bar)(A) 2.9758 (B) 5.357 (C) 3.9758 (D) 29.758
Answer» According to HENRY's LAW, P=Kxx is the mole fractionK is the henry's law constantP is the pressure in atm.Substitute VALUES in the above expression.x=76480 bar0.987 bar=1.29×10−5=55.55nn=7.16×10−4=1mol7.16×10−4 mol×1000 mmol=0.716 mmolSo, the correct option is C
