R constant with torr
WebThe answer is False. If you solve the Ideal Gas equation for n (the number of particles expressed as moles) you get: n = PV/RT. Thus, at STP, the same volume of all gases have the same number of molecules (provided the conditions are suitable for the Ideal Gas Law to apply). A more dense gas has more MASSIVE molecules, but the same number of ... WebJan 13, 2024 · Different problems will have different units, so as long as you match the unit to the corresponding R value you should be good. Here is a list with some R values: 0.0821 (atm L)/ (mol K) 0.0831 (bar L)/ (mol K) 8.314 (J)/ (K mol) 62.36 (torr L)/ (mol K) or (mmHg L)/ (mol K) 1.987 (cal)/ (mol K) Top Millicent Navarro 1I Posts: 61
R constant with torr
Did you know?
WebFeb 14, 2024 · You can figure out which R constant to use based off of the units that you are using in your problem. For example, if you are using pressure in terms of atm versus torr, you will be using a different R value. The R values work equally once the units are converted into each other. Top jaycmartinezDisc3b Posts: 56 Joined: Tue Jan 04, 2024 5:17 am WebFor pressure we use units like atm, kPa and mmHg (torr). For volumes, we may use cm 3, m 3, L or ft 3. Basically we just swap the units in the R formula, and get the gas constants with proper units. Most often we use these two gas constant units: R=8.314 L kPa K −1 mol −1 R=0.08206 L·atm/mol·K R = 62.36 L mmHg K −1 mol −1
