Given the following equation: 8 Fe + S8 → 8 FeS

a) What mass of iron is needed to react with 16.0 moles of sulfur?

7148.16 grams of iron

b) How many moles of FeS are produced?

a) 1 mole of S reacts with 8 moles of Fe

16 mole of S reacts with 128 moles of Fe

128 moles of Fe = 55.8 × 128 gm = 7142.4 gm (approx)

b) 8 moles of Fe reacts with 1 mole S to form 8 moles of FeS

128 moles of Fe reacts with 16 moles of S to form 128 moles of FeS

PLEASE MARK AS BRAINLIEST AND FOLLOW IF IT HELPED YOU!

a) answered

b) 128 moles FeS

Step-by-step explanation:

b) 16 moles of S8, original equation multiplied by 16

8 moles of FeS originally, multiplied by 16=128

Since equivalent fractions do not always have the same numerator and denominator, one way to determine if two fractions are equivalent is to find a common denominator and rewrite each fraction with that denominator. Once the two fractions have the same denominator, you can check to see if the numerators are equal.
