I was able to solve the problem but I dont know why.
problem: S + O2 -- SO2; 2.6*10^7 tons of SO2 formed--how many tons of sulfur??

how come I can use the ton-mol and dont need to convert it to g-mole??
thanks

***
I did it like this:
tons SO2 * (tonmol SO2/molecular weight SO2) *(1 ton-mol S/1 ton-mol SO2)*(molecular weight of S/1ton-molSO2)=tons of Sulfur

OKay what should have been done to solve this problem is you should have how much moles was in SO2 by using the equation $$n=\frac{ ms }{ mm }$$ (are you familiar with this?)   DONT FORGET TO CONVERT TONS TO GRAMS

then after obtaining the number of moles (n) for SO2 you should have used mole ratios to figure how much S you have then once more use n=ms/mm to find ms. that's in grams. Convert that to tonnes. that's your answer.

the point is it worked without doing what you said..i want to know why

what do you mean when you say tonmol?
