Problem- When a sample of H2S gas produced according to the equation was collected over water at 11 oC the pressure of gas above the water was 0.978 atm and its volume was 2560 mL. Calculate the mass (g) of H2S produced. Be sure to consider the vapor pressure of the water.
Fe2S3(s) + 6HCl(aq) ----> 3H2S(g) + 2FeCl3(aq)
Molar Mass (g/mol) H2S 34.082 Water Vapor Data 11 oC 2 torr Gas Constant (L atm mol-1K-1) 0.082058
