Question #617c9

Answer 1

The dilution factor is 100.

Explanation:

The dilution factor `"DF"` for a single dilution is

`color(blue)(bar(ul(|color(white)(a/a) "DF" = V_f/V_i color(white)(a/a)|)))" "`

where `V_"i"` and `V_"f"` are the initial and final volumes.

In your problem,

`V_"i" = "10.0 µL"` and

`V_"f" = "1000 µL"`

∴ `"DF" = V_f/V_i = (1000 cancel("µL"))/(10cancel("µL")) = 100`

You have diluted the sample by a factor of 100.
