On a w/v basis 1% is 1 g/100 mL or 10 g/L, so 4% is 40g/L.... -
Auto-correct made an auto-mistake which I missed. "Of" should have been "or." In both cases. Sorry about that....Leave a comment:

I've never encountered the last two terms.
Density is the actual mass divided by the actual volume. Units are commonly grams per cubic centimeter...Leave a comment:

I am not very good at "science in Customary" but I will take a cut at it. Just as I can regard a molar ppm as µmol/mol, I can regard it as pound-moles...Leave a comment:

Oops: The above is correct but you wanted per million cubic feet, so 1 ppm = 0.166 lb/MMCF for the 64.0188 g/mol gas
Also, I have to caution...Leave a comment:

Standard molar volume is 22.414 dm³ at 273.15 K, 24.055 dm³ at 293.15 K (and standard pressure).
1 ppm = 1 µmol (pollutant)/ mol (gas mixture)....Leave a comment:

Ppm ratios of gases are normally given as molar ratios, micromoles of pollutant per mole of gas mixture. You would need to know the molar mass of the...Leave a comment:

You need to know the specic gravity of density and watch your units. Obviously a cubic meter of air, water, steel, or gold have very different masses....Leave a comment:

If you look at a cross section, it is a hole with a width and depth, except there is a big 48" circle in the middle of it (the pipe). Is 48"...Leave a comment:
