This clearly should be in the chemistry section........I get approx. #50*g# #"sulfur"#.

Explanation:

And you will have to qualify what you mean by a table chart.

For all such reactions, we must first write a stoichiometrically balanced equation with respect to mass and charge......

Elemental sulfur can be burnt in air to give #SO_2(g)#, according to the following equation.......

#S(s) + O_2(g) rarr SO_2(g)#........if I was being pedantic I could write.....

#1/8S_8(s) + O_2(g) rarr SO_2(g)# but clearly the former equation reflects the stoichiometry faithfully.

We want #100*g# #SO_2(g)#, this represents a molar quantity of....

#(100.0*g)/((32.06+2xx16.00)*g*mol^-1)=1.56*mol#.

Given the 1:1 stoichiometry I must burn a #1.56*mol# quantity of elemental sulfur to get #1.56*mol# quantity of #SO_2(g)#....

i.e. a mass of #....1.56*cancel(mol)xx32.06*g*cancel(mol^-1)=50.0*g#
