According to Henry law , at constant temperature, amount of gas dissolved or we say concentration is directly proportional to partial pressure of gas at equilibrium. according to Henry law, C = KH . P Where KH = Henry constant = 0.087M/atm C = concentration On putting values, C = 0.087 × 4.53 = 0.39411 M Now we have concentration of H2S gas,molarity = no.of moles of solute ÷volume of solution in liter Volume = 875ml = 0.875L Hence, 0.39411 = moles ÷ 0.0875 Moles of H2S gas = 0.0345 Molar mass of H2S = 34 Mass of H2S = 34 × 0.0345 = 1.17 g hence mass of H2S used is 1.2 g (upto to Two significant number)
