The molecular weight of cis-2-Butene-1,4-diol [C₄H₈O₂] is 88.1056.

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: cis-2-Butene-1,4-diol [C₄H₈O₂] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a cis-2-Butene-1,4-diol molecule.
From the chemical formula, you will know different atoms and their number in a cis-2-Butene-1,4-diol molecule. Chemical formula of cis-2-Butene-1,4-diol is C₄H₈O₂. From the chemical formula of cis-2-Butene-1,4-diol, you can find that one molecule of cis-2-Butene-1,4-diol has four Carbon (C) atoms, eight Hydrogen (H) atoms and two Oxygen (O) atoms.

Step 2: Find out atomic weights of each atom (from 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 present in a cis-2-Butene-1,4-diol molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in cis-2-Butene-1,4-diol: 4
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in cis-2-Butene-1,4-diol: 12.0107 x 4 = 48.0428

Number of Hydrogen atoms in cis-2-Butene-1,4-diol: 8
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in cis-2-Butene-1,4-diol: 1.008 x 8 = 8.064

Number of Oxygen atoms in cis-2-Butene-1,4-diol: 2
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in cis-2-Butene-1,4-diol: 15.9994 x 2 = 31.9988

Step 4: Calculate the molecular weight of cis-2-Butene-1,4-diol by adding up the total weight of all atoms.

Molecular weight of cis-2-Butene-1,4-diol: 48.0428 (Carbon) + 8.064 (Hydrogen) + 31.9988 (Oxygen) = 88.1056

So the molecular weight of cis-2-Butene-1,4-diol is 88.1056.
