In summary, to calculate the mass of gas in a tank, first measure the volume of gas in the tank. Next, determine the gas's density, which can vary with temperature and pressure. Finally, use the formula: mass = volume × density. Ensure that all measurements are in compatible units to...
In the earlier analysis I presented, if we include heat transfer between the tank gas and the surroundings, we obtain: (F3V−F4m)dTdt=dmdt−UA(hv−F2)(T−Ts)where A is the surface area of the tank, U is the overall heat transfer coefficient, and Ts is the temperature of the...
Calculate the volume of 4.50 mol of SO2 (g) measured in STP. Ideal Gas Law: Unlike a solid or liquid, the particles of a gaseous substance move around at high speed in three dimensions and occupy the full volume of their closed container. The molar quantity of the gas present inside of...

I have asked two times the following question:I want to calculate the gas concentration, in ppm, in the closed chamber of volume 1025 cm3. I have a cylinder of mixture of NH3 and air with the 10 and 90% ratio respectively. we are flowing this gas mixture
(or mixture of gases) passes through a given region of space per unit time. This is in contrast to the simpler and more common measure,average cubic feet per meter(ACFM)in which the only variable of concern is simplythe volume of gasflowing through a given region of space per unit time...
