What is the value of R at STP?
If you use the first value of R, which is 0.082057 L atm mol-1K-1, your unit for pressure must be atm, for volume must be liter, for temperature must be Kelvin.
What is the numerical value of R?
0.0821The numerical value of gas constant R,in lit atm mol−1 K−1 is 0.0821.

What is r in the ideal gas law equation?
The units of Ideal gas law constant is derived from equation PV = nRT? … Pressure and Temperature must remain in the units atm and K and the Gas Law Constant remains R = 0.0821 (atm)L(mol)K .
What is the value of R in units of kPa?
If we measure pressure in kilopascals (kPa), volume in litres (L), temperature in Kelvin (K) and the amount of gas in moles (mol), then we find that R = 8.314 and it has the units kPa L K-1 mol-1.
What is the constant R?
R=0.08206Latmmol−1K−1. The gas constant R will appear in many contexts as this is a Universal constant that relates energy and temperature. A pressure times a volume is an energy. As such, you will also encounter the gas constant R in typical energy units of Joules. R=8.314Jmol−1K−1.
How do you find r in PV nRT?
P = Pressure (atm) V = Volume (L) n = moles R = gas constant = 0.0821 atm•L/mol•K T = Temperature (Kelvin) The correct units are essential. Be sure to convert whatever units you start with into the appropriate units when using the ideal gas law.
What units are used in PV nRT?
In SI units, p is measured in pascals, V is measured in cubic metres, n is measured in moles, and T in kelvins (the Kelvin scale is a shifted Celsius scale, where 0.00 K = −273.15 °C, the lowest possible temperature). R has the value 8.314 J/(K·mol) ≈ 2 cal/(K·mol), or 0.0821 L·atm/(mol·K).
What is R chemistry?
The value of the gas constant ‘R’ depends on the units used for pressure, volume and temperature. R = 0.0821 liter·atm/mol·K. R = 8.3145 J/mol·K. R = 8.2057 m3·atm/mol·K.

What is the R value for MMHG?
8.314 J/K*molIts value in S.I. unit is 8.314 J/K*mol. It is also known as universal gas or ideal gas constant. The energy value incorporated in the value of ‘R’ is the product of the pressure-volume product.
What is R in English units?
The Individual Gas Constant – R In the imperial system the most common units for the individual gas constant are ft lb/slug oR. In the SI system the most common units are J/kg K. Unit conversion: 1 J/kg K = 5.97994 ft lb/slug °R, and 1 ft lb/slug °R = 0.167226 J/kg K.
What is the R in pV nRT?
Ideal Gas Law. This law combines the relationships between p, V, T and mass, and gives a number to the constant! The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K.
