Molar mass links how much a substance weighs to how many moles (a count of particles) that mass represents.
Molar mass links how much a substance weighs to how many moles (a count of particles) that mass represents. This calculator solves for mass, moles, or molar mass, given the other two — handy for weighing out chemicals for a reaction.
How many moles are in 36 g of water (molar mass 18 g/mol)? Leaving Moles blank: Moles = 36 / 18 = 2 mol.
It sums the atomic masses of every atom in a compound's formula, weighted by count.
Grams per mole (g/mol).
It's the conversion bridge between measurable mass and moles used in chemical equations.
