_________________ turns fuschia (dark pink) in a __________.
What is phenolphthalein and base.
500
The number of grams of FeO produced when 1.25g of Fe is reacted with excess O2.
2Fe + O2 --> 2FeO
n=1.25 g/55.85 g/mol = 0.0224 mol
mole ratio = 2/2
m = nMM
= 0.0224 mol x (55.85 + 16.00 g/mol)
= 1.61 g
