Question

Question:
1. If there is 19 ml of diluent (water) in the tube and 1 ml of protein sample is added to it, what
would be the dilution of the protein sample?​

Answer 1

Answer:

To find a dilution of a single tube, use the formula: sample/(diluent + sample). The sample is the amount you are transferring into the tube, and the diluent is the liquid already in the tube. When you transfer 1 ml into 9 mls, the formula would be: 1/(1+9) = 1/10.

1/(1+19)=1/20

Answer 2

Answer:

The dilution of the protein sample is 0.05.

Explanation:

To answer this, we'll use the formula shown below:-

$\mathrm{DF=\frac{V_1}{V_2} }$         (1)

Where,

DF = a measure of the sample's dilution

V₁ = initial volume of the sample

V₂ =final volume of the sample

From the question we have,

The initial volume of the sample(V₁)=1 ml

The final volume of the sample(V₂)=19 ml+1ml=20ml

Now, by inserting the final and initial volume in equation (1) we get;

$\mathrm{DF=\frac{1}{20} }$

$\mathrm{DF=\frac{1}{20} }$

$\mathrm{DF=0.05}$

So, the dilution of the protein sample is 0.05.
