Bạn đang xem: c3h7cooh Butanoic acid [C3H7COOH] is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of Butanoic acid is 88.1056 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Carbon, Hydrogen, and Oxygen.

# CALCULATION PROCEDURE: Butanoic acid [C3H7COOH] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Butanoic acid molecule.
From the chemical formula, you will know different atoms and their number in a Butanoic acid molecule. The chemical formula of Butanoic acid is C4H8O2. From the chemical formula of Butanoic acid, you can find that one molecule of Butanoic acid has four Carbon (C) atoms, eight Hydrogen (H) atoms, and two Oxygen (O) atoms.

Step 2: Find out the atomic weights of each atom (from the periodic table).

Atomic weight of Carbon (C): 12.0107 (Ref: Jlab-ele006)
Atomic weight of
Hydrogen (H): 1.008 (Ref: Lanl-1)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

Step 3: Calculate the total weight of each atom in a Butanoic acid molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Butanoic acid: 4
Atomic weight of
Carbon (C): 12.0107
Total weight of Carbon atoms in Butanoic acid: 12.0107 x 4 = 48.0428

Number of Hydrogen atoms in Butanoic acid: 8
Atomic weight of
Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Butanoic acid: 1.008 x 8 = 8.064

Number of Oxygen atoms in Butanoic acid: 2
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Butanoic acid: 15.9994 x 2 = 31.9988

Step 4: Calculate the molecular weight of Butanoic acid by adding up the total weight of all atoms.

Molecular weight of Butanoic acid: 48.0428 (Carbon) + 8.064 (Hydrogen) + 31.9988 (Oxygen) = 88.1056

So the molecular weight of Butanoic acid is 88.1056.
