Abstract
The mole bridge: converting between two chemicals in a reaction.
Concept preview
What you will be able to do
- 01Describe the three-step stoichiometry plan
- 02Carry out mass-to-mass calculations
- 03Include gas volume and molecule counts in stoichiometry
Stoichiometry finds how much of one chemical is involved based on the amount of another. The relationship between the two runs through their moles, so picture a 'mole bridge' connecting moles of chemical #1 to moles of chemical #2. Every problem has the same shape: convert the starting information to moles of #1, cross the bridge using the mole ratio from the balanced equation, then convert moles of #2 to whatever unit is asked for.
