if all the sulphur atoms from 9.8 kgh2so4 are removed and converted to s8 than how many moles of s8 can be prepared?

Answer 1

You need to find the caps key on your computer and use it.
mols S in 9.8 kg H2SO4 = grams/molar mass = 9800/molar mass H2SO4 = estimated 100
8S ==> S8
100 mol S x (1 mol S8/8 mol S)
