Note
Simplified model: these results assume ideal behaviour (ideal gases, dilute solutions, complete reactions) and standard textbook constants. Real laboratory values vary with temperature, pressure, purity and activity coefficients. Do not rely on this for safety-critical or analytical work.

How do you calculate molar mass from a given number of moles and mass?+
Molar mass equals mass divided by moles: M = mass (g) / n (mol). It tells you how many grams correspond to one mole of that particular substance.
What units should I use for mass and moles?+
Mass should be in grams and the result comes out in grams per mole (g/mol), the standard unit for molar mass. If your mass is in milligrams or kilograms, convert to grams first or your result will be off by a factor of 1000.
Why is molar mass different for every substance?+
Molar mass is the sum of the atomic masses of every atom in the molecule's formula, so it depends entirely on the substance's composition. Water (H2O) has a molar mass of about 18 g/mol, while table salt (NaCl) is about 58.44 g/mol, because their atoms differ.
Can this calculator help me identify an unknown compound?+
Calculating molar mass from an experimentally measured mass and moles can narrow down candidate compounds by comparing the result to known molar masses on a periodic table or reference chart. It won't identify the compound by itself, but it's a key clue in qualitative analysis.
What if my calculated molar mass doesn't match the expected value?+
Small discrepancies usually come from measurement error or impure samples, but a large mismatch often means the number of moles was calculated incorrectly, or the sample contains water of hydration or contaminants. Double-check the moles calculation and sample purity before assuming the compound's identity is wrong.
