Hello!

To measure the percentage error for the amount of liquid that you have gathered using the 25mL graduated cylinder, we can use this formula:

percent error = maximum error/value of measurement x 100

where:

maximum error= is the value written in the apparatus (i.e. `+- 0.1 mL)`

*try to look for that value in your graduated cylinder

Value of measurement= is the amount of substance that you used, in our case its 10mL

Let's just say that maximum error is equal to `+-.3mL.`

` `

We can have:

percent error= 0.30 mL/10 mL x 100

= 3% error

note: Please provide the maximum error for the apparatus that you are using in order for you to calculate the percent error.

Hope this helps :)
