MOLE CONVERSIONS
The mole conversions are used to do calculations for a balanced chemical equation. The purpose of these calculations is to not have ANY left over atoms that didn't react. There are 4 ratios that we can use.
- Mole to Mass (1 mole = molar mass from the periodic table for an ELEMENT or a COMPOUND)
- Mole to Particle (1 mole = 6.02 x 10^23 atoms/molecules/f.u./ions)
- Mole to Volume (at Standard temp and pressure 1 mole = 22.4 L of GAS) For this you can use the ratio or the MOLE HOLE chart.
- Mole to Mole (from a balanced chemical equation)
