How many grams of iron (Fe) is contained in 15.8 g of Fe(OH)3?



Answer:
So basically, you need to find the moles of Fe(OH)3.

1. Find the molar mass
Fe = 55.85
O = 3 x 16.00
H = 3 x 1.008
add those together.

2. then find the moles of the compound in 15.8 grams.
(15.8grams/molar mass) = moles

3. that's how many moles of Fe you have!
g Fe(OH)3 * gravimetric factor

(15.8) * (1/1) * (55.847/ 106.86902)

= 8.257 g of Fe
