What does the R stand for in the ideal gas law (PV=nRT)? - Socratic
2014年5月25日 · However, temperature must always be in Kelvin (K), as R uses units of "K". There is a variation of the ideal gas law that uses the density of the gas with the equation PM = DRT where M is the molar mass in "g/mol" and D is the density of the gas in "g/L".
How do you decide when to use this equation: pV=nRT?
2018年6月25日 · PV = nRT P is the pressure of the gas, usually measured in kPa. V is the volume of the gas, usually measured in L. n is the amount of gas, measured in mol. R is the ideal gas constant, which equals 8.314(L*kPa)/(mol*K) T is the temperature of the gas, measured in K. Since R is a constant, there are four unknowns in this equation.
In the equation PV=nRT, what does the R and n stand for?
2018年4月24日 · Well, n="number of moles" And thus n is equal to the number of gaseous particles....i.e. which we express in units of moles. And R is the universal gas constant. There are several expressions for R.. For chemists, possibly the most useful one is R=0.0821*L*atm*K^-1*mol^-1; chemists routinely deal with litre volumes, and gram quantities, and express pressure in units of atmosphere...
How would you solve the equation PV = nRT for R? - Socratic
2015年10月28日 · How would you solve the equation PV = nRT for R? Chemistry Gases Ideal Gas Law. 1 Answer
What units should I use in the ideal gas law equation?
2015年1月11日 · The ideal gas law equation allows for the use of a wide variety of units as long as you correlate these units with those that express the gas constant, "R". The ideal gas law equation looks like this: PV = nRT, where P - pressure - the most commonly used units used to express pressure are atm, mmHg, torr, Pa, kPa, bar; V - volume - commonly used units are L, "m"^3, "cm"^3, "dm"^3; n - the ...
Considering the ideal gas law PV=nRT, what is P directly ... - Socratic
2015年7月27日 · Pressure is directly proportional to temperature and number of moles. The ideal gas law equation looks like this PV = nRT, where P - the pressure of the gas; V - its volume; n - the number of moles of gas; R - the gas constant, usually given as 0.082("atm" * "L")/("mol" * "K") T - the temperature of the gas. In order for two variables to have a …
What does the R in PV=nRT represent? - Socratic
2018年5月15日 · What does the R in PV=nRT represent? Chemistry Gases Ideal Gas Law. 1 Answer Shulgin ...
How do you find the ideal gas constant? - Socratic
2014年3月20日 · The ideal gas law uses the formula PV = nRT where P is the pressure in atmospheres (atm), V is the volume in liters (L), n is the number of moles (mol) and T is the temperature in kelvin (K). If we set up the ideal gas law for the values of 1 mole at Standard temperature and pressure (STP) and calculate for the value of the constant R, we can determine the value of the ideal gas law constant ...
What units are used in the equation pv=nrt? | Socratic
2015年11月16日 · For the ideal gas law #PV=nRT# the unit of each term is the following:. #P " in "color(green)(atm)# #V" in "color(red)(L)#
In the ideal gas law equation, #PV=nRT#, what is the value
2016年8月14日 · The Gas constant R changes according to the units you employ. Chemists typically deal with "litre" quantities of gases, and typically measure "pressure" in units of "atmospheres". Of course, both physicists and chemists tend to use "degrees Kelvin" as units of absolute temperature (mind you, there is a "Rankin" scale). Given this, for chemists, R is typically used as 0.0821*L*atm*K^-1*mol^-1 ...
