Having trouble calculating the error of a diluted solution in a 100mL volumetric flask. Concentration is 0.005 +/- 0.005M Amount of Concentrated solution: 5.0mL +/- 0.1mL Volumetric flask: 100mL +/- 0.08mL
My calculation so far is ((0.1/5)+(0.005/0.005)+(0.08/100))*.00025 I keep getting 0.0002552 as my error but the answer key is 0.00003. Whats wrong in my formula?

10 mL of bleach with an unknown concentration is added to a
100mL volumetric flask. The solution is then finished with
deionized water. 10 mL of this diluted bleach solution is then
added to an erlenmeyer flask along with 1 scoop of KI, and 5 L of
2M HCl. This solution is then titrated with Na2S2O3 until it is a
pale yellow color, then a starch indicator is added and titration
is completed until the solution is clear. If 43...

100mL of ~0.1M KMnO4solution was transferred to
1000mL volumetric flask and dilute to the mark with distilled water
but accidently I added 50mL more water (50 mL excessed, total

0.1002g of Na2C2O4 and 32.73mL
of permanganate solution were used to titrate.

A student weighs by difference 0.1956g of sodium oxalate into a
100ml Volumetric flask and dilutes to the mark 10mL of HCI and 90mL
of distilled water. The student then pipetted a 25mL aliquot of the
ocalate solution to a 125mL Erlenmeyer flask. Approximately how
many mL's of 0.02 M KMnO4 would be requied to reach the equivalence
point of the trtration?
The balanced alf reactions are:
Reduction: MnO4- + 8H+ + 5e- --> Mn2+ +

A 10.0 mL sample of liquid bleach is diluted to 100. mL in a
volumetric flask. A 25.0 mL aliquot of this solution is analyzed
using the procedure in this experiment. If 10.4 mL of 0.30 M
Na2S2O3 is needed to reach the equivalence point, what is the
percent by mass NaClO in the bleach? Hint: Percent by mass is grams
of NaClO / mass of bleach. Presume a density for the bleach of 1.00
g/mL.

When calculating the concentration of a diluted solution, a
person can use the dilution equation: Mc Vc = Md Vd
Why does Mc Vc equal Md Vd ? What is this mathematical statement
saying? Why would losing some concentrated solution from the pipet
during the preparation stage ruin this equation? Explain in
detail.

the simulation on Solution Preparation you are instructed to invert
the volumetric flask to mix the contents by covering the opening
with a gloved finger. Explain why this is a bad idea.

1.Less quantitative dilutions can also be done without a
volumetric flask, The precision of concentration is dependent on
how precise the volumes are transferred. For example a dilute
solution of HCl can be made using a precise amount of 5.0 M HCl and
distilled water. In this case the total volume of dilute HCl (V2)
is the total volume of 5.0 M HCl plus the volume of water.
Determine the volume of water in mL needed to prepare 5.0mL (V2)...
