Answer: The empirical formula is
Explanation:
Mass of C= 17.900 g
Mass of H = 1.680 g
Mass of O = 4.225 g
Mass of N = 1.228 g
Step 1 : convert given masses into moles.
Moles of C =
Moles of H =
Moles of O =
Moles of N =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C =
For H =
For O =
For N =
The ratio of C : H: O: N = 17: 19: 3: 1
Hence the empirical formula is
