The molecular weight of tert-Butanol [(CH3)3COH] is 74.1222.
To calculate molecular weight of any compound, the first step is to know the constituent atoms and their number in that particular compound. Then calculate the total weight of each atom by multiplying its atomic weight by its number. The sum of total weight of all constituent atoms will be the molecular weight of the compound. Note that the value of atomic weight may differ slightly from different sources.
CALCULATION PROCEDURE: tert-Butanol [(CH3)3COH] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a tert-Butanol molecule.
From the chemical formula, you will know different atoms and their number in a tert-Butanol molecule. Chemical formula of tert-Butanol is C4H10O. From the chemical formula of tert-Butanol, you can find that one molecule of tert-Butanol has four Carbon (C) atoms, ten Hydrogen (H) atoms and one Oxygen (O) atom.
Step 2: Find out atomic weights of each atom (from periodic table).
Step 3: Calculate the total weight of each atom present in a tert-Butanol molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in tert-Butanol: 4
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in tert-Butanol: 12.0107 x 4 = 48.0428
Number of Hydrogen atoms in tert-Butanol: 10
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in tert-Butanol: 1.008 x 10 = 10.08
Number of Oxygen atoms in tert-Butanol: 1
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in tert-Butanol: 15.9994 x 1 = 15.9994
Step 4: Calculate the molecular weight of tert-Butanol by adding up the total weight of all atoms.
Molecular weight of tert-Butanol: 48.0428 (Carbon) + 10.08 (Hydrogen) + 15.9994 (Oxygen) = 74.1222
So the molecular weight of tert-Butanol is 74.1222.
