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

$\tt DF=\dfrac{M_1}{M_2}=\dfrac{V_2}{V_1}$

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) :

$\tt D_f=\dfrac{V_f}{V_i}\\\\D_f=\dfrac{10}{0.1}=100$
