Calculate the theoretical yield of iron(III) oxide expected for this reaction if 0.50 mol of iron is reacted with excess oxygen

a_sh-v [17]

When you are dealing with mole calculations, whatever you do to one side of the equation you must also do to the other. .5Fe is 1/8th of 4Fe, so in order to determine what it will yield you must divide the given amount of Fe2O3 and divide THAT by 1/8th, leaving you with .25 mol of Fe2O3.

Convert 1.50μm2 to square meters

IrinaVladis [17]

1 micro meter = $10^{-6} meters$
1 μm ^2 = 1 μm*1μm = $10^{-6} *10^{-6} = 10^{-12}$ meters

1.5 μm^2 = 1.5 * $10^{-12}$ meters

μm^2 is a unit for surface. First you want to convert μm to meters which is unit for length and if you multiply units for length you get unit for surface.
