The dilution factor is 100.

#### Explanation:

The dilution factor $\text{DF}$ for a single dilution is

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

where ${V}_{\text{i}}$ and ${V}_{\text{f}}$ are the initial and final volumes.

${V}_{\text{i" = "10.0 µL}}$ and
${V}_{\text{f" = "1000 µL}}$
"DF" = V_f/V_i = (1000 cancel("µL"))/(10cancel("µL")) = 100#
