##### Deriving Mass from Chemical Equations
« on: July 11, 2011, 07:03:44 PM »
What mass of a sample that is 98.0 % sulfur would be required in the production of 75.0 kg of H2SO4 by the following reaction sequence?
S8  +  8 O2   ------->    8 SO2
2 SO2  +  O2   ------->    2 SO3
SO3  +  H2O   ------->   H2SO4

I'm just confused on how to apply the 98% of sulfur to each of the equations.  Thanks for any feedback!

Simple Mathematics.  You have to look how many sulfur atoms in one sulfuric molecule. If you know this then you can calculate how many molecules you can make from S8.

You have to calculate the mole of the sulfuric given by the mass.
