Using the actual density of the mixture is always the correct answer.
If the mixture is very dilute, for example contaminants in drinkable...

Only if you also measure the volume and use the two to cancel density. You are measuring and converting concentrations. The same conversion between...Leave a comment:

The mass of the sample should not be used in the calculation if you know the density. If you don't know, then you need both the mass and volume of the...Leave a comment:

I'm sorry, I missed the 1.05 g. The mass of the sample is not material. I assume the factor of 10 is dilution and correct

If the "10" is the effect of your dilution factor, that is correct. You have handled the density correctly. As I said, I'm not familiar with...Leave a comment:

I do not know the operation of gas chromatography equipment or relevance of the dilution factor of 10.
If I focus solely on the concentration...Leave a comment:

What units do you want them in? 8x103 is scientific notation and just another way to write 8000. You have 8000 in a volume of 1 µL (microliter), a millionth...Leave a comment:

I looked up some articles. All recommend using 35% food grade hydrogen peroxide to keep the quantities manageable. Unlike the weak dilutions you buy...Leave a comment:

Hydrogen Peroxide is sold as different strength solutions, so we need to know the strength you are using. We also need to know the concentration you...Leave a comment:

I'll use your figure but I caution that you need the actual density of the lot, not a specified maximum. A tonne (metric ton) is 1000 kg. The density...Leave a comment:
