Empirical Formula Problems
Due at end of Period
Slide2The compound
benzamide
has the following percent composition. What is the empirical formula?
C
= 69.40 % H= 5.825 % O = 13.21 % N= 11.57 %
2. A
component of protein called serine has an approximate
molar mass
of
105
g/mole. If the percent composition is as
follows
, what
is
the empirical and molecular formula of serine?
C
= 34.95 % H= 6.844 % O = 46.56 % N= 13.59 %
What are the empirical and molecular formulas
of a molecule
containing
65.5% carbon, 5.5% hydrogen, and 29.0%
oxygen and with a molar mass of
110.11
grams/mole?
The
percentage composition of acetic
acid(molecular mass 60.0 g/
mol
) is
found to be 39.9% C, 6.7% H, and 53.4% O.
Determine the
empirical formula
and molecular formula of
acetic acid
.
