Find the molar mass of FeO
Fe = 55.85 g/mol
O = 16.00 g/mol
Molar mass of FeO = 55.85 + 16.00 = 71.85 g/mol
Use the formula for moles
moles = mass / molar mass
moles of FeO = 2.5 / 71.85= 0.0348 = 0.035
Answer: 0.035 moles

Given:
- Mass of hydrate = 5 g
- Mass of anhydrous = 3 g
Mass of water lost = Mass of hydrate – Mass of anhydrous
Mass of water lost = 5 g - 3 g = 2 g
Answer:
2 g
