The molecular weight of Tris hydrochloride (C4H11NO3.HCl) is 157.59644.

Tris hydrochloride [C4H11NO3.HCl] Molecular Weight CalculationTris (C4H11NO3) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The Tris hydrochloride (C4H11NO3.HCl) also contains one molecule of Hydrogen chloride. The molecular weight of Tris hydrochloride is 157.59644 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Tris hydrochloride  [C4H11NO3.HCl] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Tris hydrochloride molecule.
You will know different atoms and their number in a Tris hydrochloride molecule from the chemical formula. The chemical formula of Tris hydrochloride is C4H11NO3.HCl. From the chemical formula, you can find that one molecule of Tris hydrochloride consists of four Carbon (C) atoms, eleven Hydrogen (H) atoms, one Nitrogen (N) atom, three Oxygen (O) atoms, and one molecule of Hydrogen chloride.

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 Nitrogen (N): 14.00674 (Ref: Jlab-ele007)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

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

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

Number of Hydrogen atoms in Tris hydrochloride: 11
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Tris hydrochloride: 1.008 x 11 = 11.088

Number of Nitrogen atoms in Tris hydrochloride: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Tris hydrochloride: 14.00674 x 1 = 14.00674

Number of Oxygen atoms in Tris hydrochloride: 3
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Tris hydrochloride: 15.9994 x 3 = 47.9982

Number of Hydrogen chloride molecules in Tris hydrochloride: 1
Molecular weight of Hydrogen chloride (HCl): 36.4607
Total weight of Hydrogen chloride in Tris hydrochloride: 36.4607 x 1 = 36.4607

Step 4: Calculate the molecular weight of Tris hydrochloride by adding up the total weight of all atoms.

Molecular weight of Tris hydrochloride: 48.0428 (Carbon) + 11.088 (Hydrogen) + 14.00674 (Nitrogen) + 47.9982 (Oxygen) + 36.4607 (Hydrogen chloride) = 157.59644

So the molecular weight of Tris hydrochloride is 157.59644.
