Answer:- molecular formula is .
Solution:- Percentages are given from which we will calculate the moles of each element.
moles of Pd = = 0.445 mol Pd
moles of O = = 1.78 mol O
moles of C = = 1.78 mol C
moles of H = = 2.66 mol H
Now we divide the moles of each by the least one of them. The least one is 0.445. So, let's divide the moles of each by 0.445.
Pd = = 1
O = = 4
C = = 4
H = = 6
So, the molecular formula of the compound is .
