Summary of How To Calculate The Molar Mass of a Compound - Quick & Easy!

Main Ideas and Concepts

Definition of Molar Mass:
Molar Mass connects mass with moles, representing the mass of one mole of a substance in grams per mole (g/mol).
Finding Molar Mass from the Periodic Table:
The Molar Mass of an element can be found using its average atomic mass listed on the Periodic Table.
Calculating Molar Mass of Compounds:
To find the Molar Mass of a compound, sum the molar masses of all the atoms in the molecule.

Step-by-Step Process:
1. Identify the Elements: Determine the elements present in the compound and their respective quantities.
2. Use the Periodic Table: Look up the average atomic mass for each element.
3. Multiply and Sum:
  - Multiply the atomic mass of each element by the number of atoms present.
  - Add all the results together to obtain the total Molar Mass.

Nitrogen (N): Molar Mass: 14.01 g/mol.
Fluorine (F): Molar Mass: 19 g/mol.
Ozone (O₃): Molar Mass: 48 g/mol (3 × 16 g/mol).
Sulfur (S₈): Molar Mass: 256.56 g/mol (8 × 32.7 g/mol).
Carbon Dioxide (CO₂): Molar Mass: 44.01 g/mol (1 × 12.01 + 2 × 16).
Silicon Tetrafluoride (SiF₄): Molar Mass: 104.09 g/mol (1 × 28.9 + 4 × 19).
Glucose (C₆H₁₂O₆): Molar Mass: 180.56 g/mol (6 × 12.01 + 12 × 1.008 + 6 × 16).
Calcium Phosphate (Ca₃(PO₄)₂): Molar Mass: 310.18 g/mol (3 × 40.08 + 2 × 30.97 + 8 × 16).
Vanadium(V) Hydrogen Phosphate (V₂(HPO₄)₅): Molar Mass: 581.77 g/mol (2 × 50.94 + 5 × 1.008 + 5 × 30.97 + 20 × 16).
