Error Analysis for Moles of Calcium Ions in 250mL

[xRadio]

Just a quick question about error analysis.

Moles of Calcium ions in 10 mL = 6.0 x 10-4 ± 0.5 x 10^-5 mols

I'm suppose to scale this number to Moles of Calcium ions in 250mL.
So when I multiply by 25, do I multiply the error value as well? Or does it remain the same?

Number of moles does change, so error does as well.
