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".
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 …
How would you solve for n in PV=nRT? - Socratic
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
Ideal Gas Law - Chemistry - Socratic
In the ideal gas law equation, #PV=nRT#, what is the value of the variable #'R'#? After burning 1.5g of some gas, 4.4g of CO2 and 2.7g of H2O were produced. What is this gas if at STP 1L of this gas weighs 1.34g?
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
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 …
In the equation pv=nrt, how would you solve for v? - Socratic
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 …
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 ...
In the ideal gas law, what would you use for R when P is in
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.
What are the units used for the ideal gas law? - Socratic
2013年12月25日 · The equation for the Ideal Gas Law is: PV = nRT On the whole, this is an easy equation to remember and use. The problems lie almost entirely in the units. SI units Pressure, P Pressure is measured in pascals ("Pa") — sometimes expressed as newtons per square metre ("N·m"^"-2"). These mean exactly the same thing. Be careful if you are given pressures in …
