calculate the weight of fe3o4 in 100.0g fe2o3.

given: molar mass of fe2o3 =159.69 g/mol molar mass of fe3o4 = 231.54 g/mol hint: you need two conversion factors

96.66 g of Fe₃O₄

Explanation:

In order to calculate the weight of Fe₃O₄ in 100.0 g of Fe₂O₃ we need elements in common between both substances, for instance, the mass of Fe in each one. We will use the molar mass of Fe = 55.84g/mol The conversion factors we need are:

Then, we can use proportions:

it takes on an electronical energy

the maximum mass of nh3 is nh3 in grams
