Answer: The possible molecular formula will be
Explanation:
Mass of C= 27.3 g
Mass of O = 72.7 g
Step 1 : convert given masses into moles.
Moles of C =
Moles of O =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C =
For O =
The ratio of C : O = 1: 2
Hence the empirical formula is
The possible molecular formula will be=
