Mass stoichiometry: grams to grams
Convert a mass of one species to a mass of another across a balanced equation: grams → moles → (cross the mole ratio) → moles → grams. The equation is balanced by ChemKernel, the molar masses are sourced, and every value is exact. Type the mass you get — enter a known mistake (the mole ratio flipped, ignored, or the grams→moles step skipped) and it is named for you, not offered as a giveaway to eliminate.
