Sloan[11] (pp. (1 Cu) (63.55 g/mol) + (1 S) (32.07 g/mol) + (4 O) (16.00 g/mol) = 159.62 g/mol Formula mass = 159.62 g/mol + (5 H 2 0) ( 18.02 g H 2 0/mol) = 249.72 g/mol 2. 5 H. 2. The result is constant enthalpy (H2 = 0) operation on expansion. { The following three examples of chart use are from Katzs[9] original work. precision = parseInt(precision); // make certain the decimal precision is an integer The difference between the original water and the water remaining in the gas is the mass of liquid water from condensation: 600 9 = 591 lbm/MMscf.
