Answer: 78.69 g of Fe
Explanation: Iron(III) oxide is Fe2O3. It has a molar mass of 159.7 g/mole. That consists of:
2 x Fe at 55.85 = 11.69 or 69.94%
3 x O at 16.0 = 48.0 or 30.06%
Therefore 112.5 grams will contain (112.5 g)*(69.94%) = 78.69 g of Fe
Most likely decreased birth rate and increased emigration.
A Liquid called Surface Tension.
Answer:
Atomic Number: 1
Atomic Mass: 1
Explanation:
Atomic number = # of protons
Atomic mass = # of protons + # of neutrons
Answer:
Molecular mass of NH3 = ( 14 + 3 ) = 17 g
