How many kg of iron and how many kg of sulfur does 100 kilograms of iron sulfide (FeS) contain if the relative atomic weight of iron is 52 and sulfur 32?

Correct answer:

m1 =  61.9 kg
m2 =  38.1 kg

Step-by-step explanation:

m=100 kg Fe:S m1:m2 = 52:32  m1+m2 = m  d=52+32m=52+32100=21251.1905 kg  m1=52 d=52 2125=2152 25=211300=211300 kg=61.9 kg
m2=32 d=32 2125=2132 25=21800=38.1 kg
