Question

Aliquot is 15 ml and i made volume makeup upto 50ml.what will be its dilution factor?

Answer 1

The dilution factor is 3.3 or 1:3.3.

Explanation:

The formula for the dilution factor `"DF"` is

`color(blue)(bar(ul(|color(white)(a/a)"DF" = V_text(f)/V_text(i)color(white)(a/a)|)))" "`

where `V_text(f)` and `V_text(i)` are the final and initial volumes.

Thus.

`"DF" = (50 color(red)(cancel(color(black)("mL"))))/(15 color(red)(cancel(color(black)("mL")))) = 3.3`

Scientists often express the dilution factor as a reciprocal, as in:

`"DF" = 1:3.3`
