1) An enzyme has one iron atom per molecule and contains .335% iron by mass. Calculate the molar mass of the enzyme. (NA = 6.022 x 10^23 mole^-1)
2) Given that the Cl-F bond has 11.2% ionic character, and given the information below, calculate the dipole moment of Cl-F that one would expect to measure.
Dipole moment: u = Q x d
Bond length: 1.27 x 10^-10
1 D (Debye) = .336 x 10^-30 C m
1 e = 1.6022 x 10^-19 C

this is exactly my exam from chem too. i cant get the first one either.
but the second one.
1.6022 * 10^-19 x 1.27 * 10^-10 = 2.0347 * 10^-29. divide that by 3.336 * 10^-30 and you get 6.09. so then your the percent ionic character formula and solve for x
x/6.09 = .112 (11.2%) solve for X and you will get .683
