The short form of PPM is parts per million. It is mainly the concentration of solid objects. PPM is used to calculate the measurement of the quantity by weight. Generally, this is the manner of concluding the traces of contaminants and food ventures. The subjects such as physics, chemistry, and engineering conclude the abbreviation PPM and are used to describe the notions as per the no-dimensional quantities. On the other hand, the short form of PPMV is parts per million volume.
It is concentrated with gaseous substances. PPMV is used to calculate the amount of gaseous substance that is present in the atmosphere. Also, sometimes it is used to measure liquid substances as well, where one million parts per volume of a liquid element get dissolved in the air. In the science and engineering courses, PPM is used to measure the pollutants in the soil and sediments. It is the value of measurement of weight, by which the units of contamination are concluded.
PPM is concentrated with solid substances, which are dissolved in the solids and liquid. Posted 03 June - PM. I have never actually seen those units used anywhere and would in fact try to avoid any "parts-per" units , but if you are talking about an ideal gas: At the same temperature and pressure, every mole of every gas has exactly the same volume, so ppmv and ppmmol should be the same.
