**Chemistry**

The activity of a stock isotope is 10,000 DPM/0.10mL. If 0.25 ml of this stock is placed in 2.50 ml of water, what is the activity in the diluted specimen? My guess is that I just multiply the 10,000 DPM by the 1/10 dilution factor. I then come up with 1,000DPM/0.10ml. Does th...

**Chemistry**

We had to calculate the resolution between to peaks resulting from an HPLC assay using an internal standard for determination of an analyte "x". I came up with 2.6, which is considered good resolution. Now we are supposed to calculate the concentration of the unknown...

**Chemistry**

I have no idea where to even start with this. It seems like it should be simple, but I have no clue. The question is... "In serum, about 55% of total serum calcium is bound. The measurement of ionized (free) calcium with an ISE is 1.10 mM. What is an estimate of the total...

**Laboratory (math, chemistry)**

Most analytic methods are subject to drift. Describe a system which could be used to determine the rate of drift of an analytic method.

**Chemistry/Normal Distributions/Math**

I might have figured it out and it was easier than I though it was if I'm correct. Does this look right?.... Lower Limit = mean - 2SD and Lower Limit = 9.2 mg/dl 9.2 = ((9.2+10.2)/2) - 2SD 2SD = 0.5 SD = 0.25??

**Chemistry/Normal Distributions/Math**

I'm confused on how to calculate the standard deviation for this... The 95% confidence limit for calcium in control sera is reported as 9.2-10.2 mg/dl. Calculate the value for one standard deviation and the coefficient of variation for this data.

A triangle has points A(1, 2), B(1, 6), and C(3, 6) and is reflected over the x-axis and then over the line y = x. A"B"C" are the coordinates of the reflected image. What is the A" coordinate?

**Chemistry PLEASE HELP!!**

Test tube one had 5mL of HgCl2, and for the first reaction I added 5 drops of SnCl2. I did the exact oppisite for test tube two. Then I added 5mL of SnCl2 to test tube one for the second reaction, and 5mL of HgCl2 to test tube two.
