MHB Calculation of concentration unit

AI Thread Summary
The discussion revolves around calculating the correct concentration unit after adding a substance with a density of 1.020 kg/m3 at a rate of 800 µL/L to a sample. The substance is 60% w/w, leading to confusion about whether the final concentration should be expressed as 490 µg/L or 490 mg/L. Clarification is sought regarding the use of "u" to denote micro (µ) for microLitres and microGrams. The participants aim to determine the accurate concentration unit based on the provided data. The focus remains on resolving the concentration unit for the sample after the addition of the substance.

I would like some help in working out the correct unit of concentration in the question below please.

I added a substance which has a density of 1.020 kg/m3 to a sample at a rate of 800 uL/ L of sample

The substance is also 60% w/w.

Will the final concentration in the sample be in 490 ug/L or 490 mg/L?

Thanks

Are you using "u" to represent the greek letter $\displaystyle \begin{align*} \mu \end{align*}$? If so, the units are "microLitres" and "microGrams", correct?
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
