First we need to calculate the number of moles of FeS
:
number of moles = mass (grams) / molecular mass (g/mol)
number of moles of FeS
= 198.2/120 = 1.65 moles
From the chemical reaction we deduce that:
if 4 moles of FeS
produces 8 moles of SO
then 1.65 moles of FeS
produces X moles of SO
X = (1.65×8)/4 = 3.3 moles of SO
Now we can calculate the mass of SO
:
mass (grams) = number of moles × molecular mass (grams/mole)
mass of SO
= 3.3×64 = 211.2 g
Answer:
Answer: 2.5 mol O2 are needed to make 5 mol H2O, assuming H2 is in excess.
Explanation:
S, P.
S is a sphere
P is an infinity
