Balancing an equation with multiple solutions
Posted: Sun Feb 24, 2008 12:32 pm
I'm trying to balance the equation H2S + CS2 + O2 = H2O + SO2 + CO2
The solution I got is 2H2S + CS2 + 6O2 = 2H2O + 4SO2 + CO2
First, is this correct? Then the question is this:
A 10g mixture of H2S and CS2 was burned in oxygen to form a mixture of H2O, SO2 and CO2. The dried mixture on being separated into its pure components yielded 0.275mol of SO2 and 0.0774mol of CO2. What mass of H2S was there in the original mixture?
I tried calculating the mass of SO2 and CO2 and then, using those answers I tried calculating the moles of H2S and CS2 by taking the total mass and the total molar mass of H2S and CS2. But clearly that didn't that didn't work. What is the first step to solving this equation? (Tell me the first step and then let me try to go from there. If I need more help I'll be back.)
Thanks,
Kristina
