Question

20mL 25% HNO3
To make .20ppm Zn: Pippet_______mL 10.00ppm Zn dilution 100 mL.

Answer 1

In the lab you will prepare a series of zinc standard solutions by diluting a stock solution to a final volume of 100 mL. Calculate the volume (in mL) of a 10.00 ppm Zn stock solution you would need to prepare 100 mL of each of the following Zn standard solutions

Answer 2

You can use the M\(_1\)V\(_1\) formula.

Answer 3

for the first one?
\[\frac{10.00mg}{L}*V=\frac{.20mg}{L}*100mL\]
like this?

Answer 4

that would just be 2 mL
