My guess is the conductance of X w/w% KCl is well-known + KCl is cheap.

You need to use exponential decay (f(t) = A + B*exp(C*t)). You also need the halflife of ^{40}K and ^^{14}C - do ypu know about all of this?

Excel (if your numbers are in cell A1 to A20): =stdev(A1:A20)
"By hand":
1) Find the mean (I will call this X)
2) For every number (Xi), calculate (Xi - X)^2 (that is, the difference between the...

Extremophiles is not the scientific name of archaeabacteria - extremophilicity is the "love" of extreme environments, but not only archaeabacteria are of this type. Some ordinary bacteria are...

Do you mean:
1) Joe completes 25 jobs successfully.
2) QC evaluates 8 of the jobs
3) Joe fails in 5 of the 8 jobs
?
Because then I would look at things such as mean and variance to judge if...

1) Reset the UV spectrophotometer at the desired wavelength with a blank sample (pure solvent, no analyte and same test procedure as the other samples)
2) Make 5-10 standard solutions of your...

EDTA complexbinds calcium and is not used for pH titration but colourimetric titration. Hslove, you need to have a reaction scheme or similar, do you have that?

I'm not an expert in anaesthetics, but my guess is that it needs to be polar enough to be transported in the blood but apolar enough to cross the cell membranes, the myelinated nerves or blood-brain...

It really depends on your matrix (if you can, make a scan on your spectrophotometer) - but try 257 nm.

Actually, the answer is much morer "coloured". Oxygen is only one of a couple gasses that allow things to burn - or oxidizes things. Fluorine and chlorine are the two other candidates.
Other gases...
