About Molar Mass of Caffeine (C8H10N4O2)

Calculate the molar mass of Caffeine (C8H10N4O2) with a per-element breakdown. The parser handles parentheses and hydrate dots. The calculation uses M = Σ (atomic weight × subscript). Why it matters: Molar mass, limiting reagent and yield are the backbone of quantitative chemistry. A miscounted subscript or the wrong limiting reactant throws off every downstream amount. Caffeine — formula C8H10N4O2. Edit the formula to compute any compound. Before you trust the number, double-check: miscounting atoms inside parentheses or hydrates; assuming the reactant you have less of (by mass) is limiting; forgetting to balance the equation first. Everything is computed on your own device — nothing you enter is uploaded — so the tool is safe for unpublished sequences, proprietary formulations and sensitive measurements, and easy to cite in a methods section or lab SOP.
