Mass-Mole Stoichiometry
mass of given → moles of given → moles of unknown
How to Perform Mass-Mole Stoichiometry Calculations
Sn(s) + 2HF(g) → SnF2(s) + H2(g)
How many moles of HF are required to react completely with 128 g of Sn?
(previous example)
75.0 g Sn x 1 mol Sn / 118.69 g Sn x 2 mol HF / 1 mol Sn = 1.26 mol HF
