Question #a18e4

Answer 1

The dilution factor will be 500, or 1:500.

Basically, you start with the volume of steel-acid solution you have in the `"100-mL"` flask. For a solution, the dilution factor is defined as the ratio between the final volume - after the dilution - and the initial volume - before the dilution

`"DF" = V_"final"/V_"initial"`

Your initial volume before the dilution will be `"1 mL"`, the aliquot you take from the solution you've prepared. After you dilute the aliquot, the final volume will be `"500 mL"`. As a result,

`"DF" = V_"final"/V_"initial" = "500 mL"/"1 mL" = "1:500"`

This is the equivalent of adding `"499 mL"` to your `"1-mL"` aliquot for a dilution factor of 1/500.
