Solve Titrimetric Analysis: EDTA & Zinc in Alloy Solution

[ricky912]

Homework Statement

Hello, please help me with this problem.

I've titrated EDTA 0.0100 M into a 10.0 mL aliquot of an alloy solution. My entire alloy same is 250.0 mL.

The EDTA reacted with zinc in a 1:1 ratio, and my best volume is 11.30 mL.

I need to find the moles of EDTA, which I believe I've found.
The moles of zinc in my 10 mL aliquot.
And the total moles of zinc in my 250.0 mL sample.

Homework Equations

The Attempt at a Solution

So far I've found my moles of EDTA in my 11.30 mL.

11.30 ml (1L/1000 mL) = 0.0113 L/EDTA

0.0113 L/EDTA (0.0100 mole/L) = 0.000113 moles of EDTA

After that I'm stuck. Please help me out.
