Question 1

What is a Molar Mass Calculator?

Accepted Answer

Molar mass is the mass of one mole (6.022 × 10²³ particles) of a substance, expressed in grams per mole (g/mol). It equals the sum of the atomic masses of all atoms in the molecular formula. Molar mass is essential for stoichiometry — calculating how much of each substance reacts or is produced in a chemical reaction.

Question 2

How does the Molar Mass Calculator work?

Accepted Answer

Molar mass = sum of (atomic mass × count) for each element Then: Atomic masses are from the IUPAC periodic table (in amu = g/mol) Then: H₂O: 2 × 1.008 + 16.00 = 18.016 g/mol Then: Avogadro's number: 1 mole = 6.022 × 10²³ molecules.

Question 3

Can you give an example of how to use the Molar Mass Calculator?

Accepted Answer

Example: Input H₂O (water) gives a result of 18.02 g/mol (2H(1.008) + O(15.999) = 18.015).
