Jul 30, 2018 · $\mathrm{atm \cdot L}$ is a derived unit for energy. Pressure is defined as being force/area, and volume is distance cubed. Pressure is defined as being force/area, and volume is distance cubed. If you multiply out the units of these quantities, you can see it is equivalent to force times distance, i.e. work , measured in energy.
gas laws - What is litre atm? - Chemistry Stack Exchange
May 14, 2017 · As $\pu{atm}$ is a multiple of $\pu{N//m^2}$ and $\pu{L}$ is a multiple of $\pu{m^3}$, then $\pu{L atm}$ is a measure of joules, the unit of energy, which is $\pu{kg m^2//s^2}$ in base SI units. Share
The unit of energy, 1 dm³ atm, is equal to how many calories?
Oct 30, 2015 · General Gas Constant, $\mathcal{R} = 0.0821\:\mathrm{dm^3\cdot atm\cdot K^{-1} mol^{-1}}$ General Gas Constant, $\mathcal{R} = 1.989\:\mathrm{cal\cdot K^{-1} mol^{-1}}$
What are the units of Kc and Kp? - Chemistry Stack Exchange
Jan 3, 2019 · Also both of them are ratios of respective quantities [ ratio of molarity(s) in Kc and ratio of pressure(s) in Kp], so they should be dimensionless according to dimensional analysis. But in some places I have seen units mentioned along with both Kc and Kp. It is quite confusing and I don't see any uniformity in this. Anyone please help.

May 11, 2023 · Use whichever value of R has the most common units to help avoid stoichiometry. But you have to use the units as written. Also you misread the table. Should be first two divided by second two. Not all 4 multiplied. So R has to be written as a constant in the units of 0.0821(L * atm / K * mol) “0.0821 Latm/Kmol” You cant use 0.0821. But also ...
About the use of pascal or atmosphere in chemistry
Nov 22, 2019 · Generally, you can work with any units you like; however, this requires the use of conversion factors. The use of conversion factors is never required when only coherent SI units are used; therefore, the use of coherent SI units (the SI base units and the SI coherent derived units, including those with special names) are preferred.
What is the difference between the units 'torr' and 'mm of Hg'?
Apr 8, 2015 · The two units torr, and mm of Hg were the same until they were redefined. The torr was named after the Italian Evangelista Torricelli. 1 atmosphere is $101325\ \mathrm{Pa}$. The torr is defined as $1/760$ of an atmosphere. This is equal to $133.322\overline{368421052631578947}~\mathrm{Pa}$, which periodically infinitely repeats.
Why is the volume of one mole of gas 22.4 or 22.7 dm3?
Oct 3, 2024 · R is a linear proportionality constant between p, V, T and n and can be expressed in a variety of units, for instance energy per unit temperature and amount of substance ($\pu{8.31446261815324JK^{−1}mol^{−1}}$).
What does the ‘−1’ superscript mean in units?
Oct 22, 2014 · The combination of units usually means what common sense would read them as. So $\pu{1m^2}$ is equivalent to a square area with the side length being $\pu{1m}$. $\pu{1 N\cdot m}$ is equivalent to a force of one newton applied over the distance of 1 meter (with a lever). And $\pu{1m/s}$ means travelling one meter per second. While more complex ...
Two ways to calculate dissolved oxygen - Chemistry Stack Exchange
Jun 27, 2018 · Note that the "% by volume"/100 for dry air also corresponds to the partial pressure in atmospheres. For air saturated with water at 25 C, the vapor pressure of water, according to Wikipedia, is 0.0313 atm. The second column is calculated by multiplying all dry air values by (1-0.0313)=0.9687.
