Given the following equation: 8 Fe + S 8  8 FeS What mass of iron, Fe, is needed to react with 16.0 grams of sulfur, S 8 ?

Explanation:

so u can work out the amount of moles of S8 by using

moles=mass/mr

=16/32.1=0.498moles

then use the molar ratio of

S : Fe

1:1 so the moles of Fe is the same 0.498

The use the equation

mass = mr x moles

=55.8 x 0.498

=27.78

so 27.8 g

hope this make sense :)

i dont know the answe

you gotta add the following molecules so we can give u an answer
