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".

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 …

2018年6月18日 · n=(PV)/(RT) Given PV=nRT (and assuming neither R nor T are zero) rArr color(blue)((PV)/(RT))=(nRT)/(RT)=color(blue)n

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 …

2015年12月13日 · By applying a little algebra. So you have the original equation, PV = nRT. To get the V, you must multiply both sides by P. Therefore, (cancel PV)/cancel "P" = (nRT)/P or V = (nRT)/P Now you can check if the equation above is correct by recalling the various principles in …

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 …

2015年10月26日 · For chemists, R = 0.0821 *L*atm*K^-1 *mol^-1, the value is usually most useful in that both litres and atmospheres are handy units (more so than m^3 and Pascals). When pressure is measured in Pascals, R = 8.314*m^3*Pa*K^-1mol^-1. Note here that volume is measured in m^3; 1 m^3 = 1000 L.

2014年10月18日 · The calculations for the ideal gas law are comparison of the Pressure and Volume of gas based upon amount and temperature. The basic formula is PV = nRT where P = Pressure in atmospheres (atm) V = Volume in Liters (L) n = of moles (mol) R = the Ideal Gas Law Constant T = Temperature in Kelvin (K) The value n is the amount of the gas measured as …
