Answer : The chemical formula for the given compound is
Explanation : Given,
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 = 45.43 g
Mass of = 54.57 g
Molar mass of = 18 g/mole
Molar mass of = 129.9 g/mole
To formulate the chemical formula, we need to follow some steps:
Step 1: Converting the given masses into moles.
Moles of water =
Moles of =
Step 2: Calculating the mole ratio of the given molecule.
For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 0.4201 moles.
For =
For Carbon =
Step 3: Taking the mole ratio as their subscripts.
The ratio of = 1 : 6
The chemical formula for the given compound is
Hence, the chemical formula for the given compound is
