Different Formulas for Quantitative Chemistry and Mole Conversion

For this unit of quantitative chemistry, there are 3 key formulas for mole conversion that you need to remember.

Concentration and Volume

Formula triangle to find moles, concentration and volume

Different units of measurement for this formula triangle is:

• Concentration – Molarity
• Volume – dm³ or litres
  • Avogadro’s Law is that 1 mole of any gas occuplies the same volume under the same conditions and, at room temperature and pressure, 1 mole of gas is always 24 litres. Molar volume is the volume of 1 mole of gas
  • Room Temperature = 298K or 1 atmosphere (atm)

Mass and Formula Mass

Formula triangle to find out mass, moles and formula mass

Different units of measurement for this formula triangle is:

•  Mass = grams , kilograms, etc

No. Of Particles

Formula triangle to find out no. of particles and moles with Avogadro’s number

Density

This last triangle isn’t for mole conversion, but it’s helpful to know just in case.
