Beyond the Answer
To find the chemical formula of progesterone, we start by determining the moles of
and
produced in combustion analysis.
-
Calculate the moles of
: -
Calculate the moles of
: -
From the moles of
, we deduce the number of moles of carbon ©: -
From the moles of
, we deduce the number of moles of hydrogen (H): -
Calculate the mass of carbon and hydrogen:
- Mass of carbon ©:
- Mass of hydrogen (H):
-
Calculate the mass of oxygen (O) in the sample:
-
Calculate the moles of oxygen:
Now we have the moles of each element:
- C: 0.126 mol
- H: 0.180 mol
- O: 0.0124 mol
- Find the simplest whole number ratio:
- Divide by the smallest number of moles (0.0124 mol):
Thus, rounding to the nearest whole numbers gives us:
- C: 21
- H: 30
- O: 4
The empirical formula for progesterone can be expressed as:
In conclusion, the chemical formula for progesterone is
