Make small talk and become his friend get to know him if he opens up he trust you and then you take it from there.
The grams of FeO that would be needed to make 234.2 grams of Fe is
1204.42 grams
<u><em> calculation</em></u>
4 FeO → Fe₃O₄ +Fe
Step 1: find the moles of fe
moles = mass /molar mass
from periodic table the molar mass of Fe = 56 g/mol
moles = 234.2 g/56 g/mol = 4.182 moles
Step 2: use the mole ratio to determine the moles of FeO
FeO: Fe is 4:1 therefore the moles of FeO =4.182 moles x4 =16.728 moles
Step 3: find the mass of FeO
mass = moles x molar mass
The molar mass of FeO = 56 +16 = 72 g /mol
mass = 16.728 moles x 72 g/mol= 1204.42 grams
C but I’m not sure sry if I’m wrong
30.58 grans of Calcium ...
