69.9%
Explanation:
To find the mass percentage of iron in the compound in Fe₂O₃, we would go ahead to express the given molar mass of the iron to that of the compound.
Mass percentage = 
x 100
Molar mass of Fe = 55.85g/mol
Molar mass of O = 16g/mol
Molar mass of Fe₂O₃ = 2(55.85) + 3(16) = 159.7g/mol
Mass percentage = 
= 69.94% = 69.9%

The answer would be .40008L
The word milli- translates to
units. In this case, we have liters as our base unit. So a milliliter is
Liters or you can say that there are:
1,000 mL in 1 L.
As I understand, you are trying to convert 400.08mL to L.
So this is how you are going to get it:
