Relative Molecular Mass of Compound Solution

STEP 0: Pre-Calculation Summary

Formula Used

Relative Molecular Mass = Mass of Molecule/(1/12*Mass of Carbon-12 atom)
M_r = M_molecule/(1/12*M_C-12)
This formula uses 3 Variables

Variables Used

Relative Molecular Mass - Relative Molecular Mass is defined as the average mass per molecule of an specific isotopic composition to 1/12 the mass of an atom of C-12.
Mass of Molecule - (Measured in Kilogram) - Mass of Molecule is defined as the average mass of the a molecule of a specific isotopic composition.
Mass of Carbon-12 atom - (Measured in Kilogram) - Mass of Carbon-12 atom is defined as the mass of the atom of the Carbon-12 isotope.

STEP 1: Convert Input(s) to Base Unit

Mass of Molecule: 18.01528 Gram --> 0.01801528 Kilogram (Check conversion here)
Mass of Carbon-12 atom: 12.0116 Gram --> 0.0120116 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_r = M_molecule/(1/12*M_C-12) --> 0.01801528/(1/12*0.0120116)

Evaluating ... ...

M_r = 17.9978820473542

STEP 3: Convert Result to Output's Unit

17.9978820473542 --> No Conversion Required

FINAL ANSWER

17.9978820473542 ≈ 17.99788 <-- Relative Molecular Mass

Relative Molecular Mass = Mass of Molecule/(1/12*Mass of Carbon-12 atom)
M_r = M_molecule/(1/12*M_C-12)

Why do we need to find the Relative Molecular Mass?

Relative molecular mass is used as the mass of the molecules when the mass of the molecule are very small.
Therefore there is a need to be take them relative to some other elements.
Relative Molecular Mass is a ratio and it is thus unitless.

What is Molecular Mass?

The average mass per molecule of a specified isotopic composition of a compound is known as the molecular mass. As it a simply mass, it carries the unit of mass (kg or g).
Mass of a molecule (m) = Relative Molecular Mass * Unified Atomic Mass Unit.
