Protons because each element has a different number. Example, Oxygen has 8, Nitrogen has 7, Carbon has 6, etc.
Answer: Empirical formula is
Explanation:
If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of C= 60.87 g
Mas of H = 4.38 g
Mass of O = 34.75 g
Step 1 : convert given masses into moles.
Mass of C =
Moles of H =
Moles of O=
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C =
For H =
For O =
The ratio of C:H:O= 2 : 2: 1
Hence the empirical formula is
