∙ 7y agoThat depends on the system of units used. In standard SI units, it is about 8.31 J/(K x mol). If you use this value, all units must be in standard SI units: pressure in pascal, volume in cubic meters, amount of substance in moles, temperature in kelvin.
The Wikipedia article on "gas constant" lists the value of R for other units. For example, you might want to use liters for volume, and atmospheres, or perhaps torr, for pressure.

Do you convert kPa into Pa when dealing with ideal gas law?
You COULD... since theoretically the "R" value is a constant and so is arbitrary.. but to keep it simple.. use the kPa in the ideal gas law.. with R as 8.314
What is R in the ideal gas law equation?
the ideal gas constant D:
How do you choose which R value to use in ideal gas laws?
units
How is the combined gas law modified to form the ideal law?
The ideal gas law is:PV = nRT,where:- P is pressure- V is volume- n is moles of substance- R is the gas constant- T is the temperature
Do you have to convert grams to moles for the ideal gas law?
Yes. You should convert grams to moles in order to use the ideal gas law. The units of the other variable, R (gas constant) has moles in it.

Identify the gas law that is used to describe gas behavior under a specific set of circumstances.?
Charles' Law and other observations of gases are incorporated into the Ideal Gas Law. The Ideal Gas Law states that in an ideal gas the relationship between pressure, volume, temperature, and mass as PV = nRT, where P is pressure, V is volume, n is the number of moles (a measure of mass), R is the gas constant, and T is temperature. While this law specifically applies to ideal gases, most gases approximate the Ideal Gas Law under most conditions. Of particular note is the inclusion of density (mass and volume) and temperature, indicating a relationship between these three properties.The relationship between the pressure, volume, temperature, and amount of a gas ~APEX
What is ideal gas constant r?
It is the value of the constant which appears in an equation relating the volume, temperature and pressure of an ideal gas. Its value is 8.314 4621 Joules/(Mol K).
What is the direct relationship between volume and temperature of an ideal gas sample?
The ideal gas law is: PV = nRT, where P = pressure, V = volume, n= number of moles, R = ideal gas constant, T = Temperature in K.

Which law is used to calculate the number of moles in a contained gas?
in normal conditions (0 degrees Celsius and pressure of 1atm) 1 mole of any gas has a volume of 22,4 litres. so use the formula n=V/Vm n - amount of moles V - volume of gas Vm =22,4l/mol
What three laws are used to make the combined gas law?
The Ideal Gas Law comes from a combination of the following simple gas laws : ( 1 ) Boyle's Law ( 2 ) Charles' Law ( also known as Gay-Lussac's Law ) ( 3 ) Avogadro's Law These combined to give the Ideal gas Law: PV = nRT where P = absolute pressure V = volume n = moles R = universal gas constant T = absolute temperature Two commonly used values of R are given below : R = 0.08206 atm - L per gmol - K R = 10.73 psia - cu ft per lbmole - R
