all the C ends up as CO2
mg of C = (12.011/44.011) x 33.5 mg CO2 = 9.142 mg C
all of the H ends up as H2)
mg H = (2.016/18.016) x 41.1 mg H2O = 4.599 mg H
mg N = 35.0 - 9.14 - 4.60 = 21.26
CxHyNz represents the empirical formula
where x = moles of C atoms, y = moles of H atoms, and z = moles of N atoms in (1 mole of) the molecule
Calculate the moles of C, H, and N that you found.
Determine the ratio of the moles x : y : z
Do that and then look at my calculations-
9.14 mg C / 12.011 mg/mmol = 0.76 millimol C
4.60 mg H / 1.008 mg/mmol = 4.60 millinol H
21.26 mg N / 14.006 mg/mmol = 1.52 millimol N
divide by the smallest number (0.76)
C = 1
H = 6
N = 2
