    Hello, how long does it really takes for the entire experiment? And each stage reflux, crystallisation and recrystallisation?

    Hello what is the yeild produced

    • @DrGSR
      @DrGSR Год назад

      Yeild = experimental mass of phenol benzoate/ theoretical mass of phenol benzoate. *100
      = experimental mass/2.254. *100
      [1ml of phenol theoretically gives 2.254g of phenol benzoate.].
