quantitative chemistry

• give equation of moles

  moles = mass / Mr
• give equation of volume of gas

  volume of gas = mass/Mr x 24 or moles x 24
• give equation of concentration 


  concentration = mass/volume or moles/volume
• give equation of atom economy

  atom economy = Mr of desired product/Mr of total product x 100
• give equation of percentage yield

  percentage yield = mass of product formed/max theoretical mass of product x 100
