(formula 2S+2H20+302 ---> 2H2S04 )

sulfuric acid is h2so4. convert 1600 kg to g so times by 1000. then take that number in grams and times by the molar mass of of sulfur (gSx1mol S/gS) then convert to moles of H2SO4 by using your balanced chemical equation(coefficients), with moles of S on bottom, moles of H2SO4 on top. everything cancels and your left with moles of sulfuric acid that you could make. if you need to take it another step to grams then you would then just use the molar mass of sulfuric acid.

formula: 2S+2H20+302 ---> 2H2S04
molar mass of sulphuric acid: mm (g/mol)
1600kg x (1000g/1kg) x (1 mol/mm) x (2 moles of S/2 moles of sulphuric acid)= number of moles of sulphuric acid

If you're putting moles into sulphuric acid I'm gonna get the animal rights people onto you.
Shame on you!

moles= mass/molar mass
moles sulphuric acid= mass in g/ molar mass
moles '' ''= 1,600,000g / molar mass
moles sulphuric acid= 1,600,000g/32
moles sulphuric acid = 50,000

you divide 1600 by the Relative atomic mass
make the ratios equal
multiple the number of moles by the relative atomic mass.

find out the Mr value from a periodic table. then divide mass/Mr value, et voila!
