Please solve parts B and C. I know how to do the mass to mole conversions. I did dof with regards to atomic species.

Single Reactor/Reaction: The following reaction occurs in a sulfur recovery reactor 2H2S + SO2 35 + 2 H2O The composition of the feed to the reactor in mass % is as follows: 40% H2S; 50%802 and 10% Inert gas (1). Molecular weight of inert, I = 10; H2S=34; SO2=64; S=32; H20=18 BFD, label and DOF b. Calculate the % excess of the excess reactant. Determine the composition of the stream exiting the reactor if the percent conversion of the limiting reactant is 50%. a. c
