Nonadecane (C19H40) is an organic compound of two elements: Carbon, and Hydrogen. The molecular weight of Nonadecane is 268.5233 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Nonadecane [C19H40] Molecular Weight Calculation
Step 1: Find the chemical formula and determine constituent atoms and their number in a Nonadecane molecule.
You will know different atoms and their number in a Nonadecane molecule from the chemical formula. The chemical formula of Nonadecane is C19H40. The chemical formula shows that one Nonadecane molecule consists of nineteen Carbon (C) atoms and forty Hydrogen (H) atoms.
Step 2: Find out the atomic weights of each atom (from the periodic table).
Step 3: Calculate the total weight of each atom in a Nonadecane molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Nonadecane: 19
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Nonadecane: 12.0107 x 19 = 228.2033
Number of Hydrogen atoms in Nonadecane: 40
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Nonadecane: 1.008 x 40 = 40.32
Step 4: Calculate the molecular weight of Nonadecane by adding up the total weight of all atoms.
Molecular weight of Nonadecane: 228.2033 (Carbon) + 40.32 (Hydrogen) = 268.5233
So the molecular weight of Nonadecane is 268.5233.
