Question

What is the dilution factor if you add a 0.1ml aliquot of a specimen to 9.9 dilutent

Answer 1

The dilution factor : 100

Further explanation

The dilution factor(DF) : ratio of concentration of stock solution and diluted solution or ratio of the volume of final solution to the initial volume from stock solution

From equation of dilution :

M₁V₁=M₂V₂

`\tt DF=(M_1)/(M_2)=(V_2)/(V_1)`

Volume of aliquot = 0.1 ml

Volume of diluent = 9.9 ml

So final volume :

`\tt V_f(final~volume)=volume~aliquot+volume~diluent\\\\V_f=0.1+9.9=10~ml`

The dilution factor (DF) :

`\tt D_f=(V_f)/(V_i)\\\\D_f=(10)/(0.1)=100`
