Please help with the following question ...
For the reaction S + O2 = SO2
a) What mass of SO2 is formed by reacting 6.42g of S with O2 ?
I struggled with the above answer I kept getting 12.4g if anyone can shed some light on this issue Id be greatly appreciated .
basic chemistry question ? watch

how are you getting 12.4? Can you give any details on what you did?
Also, been a while since I've done these type of problems. But 1mol of S + 1mol O2 = 1mol SO2
so find out how many moles of S is in 6.42g
Then that same number of moles of SO2 should be produced (assuming O2 is in excess)
rearrange n = m/Mr to find out what m (of SO2) is.Last edited by Et Tu, Brute?; 10-05-2016 at 20:26.
