## What is the R constant for air?

The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K. This means that for air, you can use the value R = 287 J/kg·K.

**What is the significance of the volume 22.4 L?**

Always the Standard temperature and pressure (STP) is defined as 0°C (273.15 K) and 1 atm pressure. The molar volume of a gas is the volume of one mole of a gas at STP. At STP, one mole (6.02 × 1023 representative particles) of any gas occupies a volume of 22.4 L.

### What is R in PV NRT?

In the equation PV=nRT, the term “R” stands for the universal gas constant. The universal gas constant is a constant of proportionality that relates the energy of a sample of gas to the temperature and molarity of the gas.

### How do you find R?

Steps for Calculating r

- We begin with a few preliminary calculations.
- Use the formula (zx)i = (xi – x̄) / s x and calculate a standardized value for each xi.
- Use the formula (zy)i = (yi – ȳ) / s y and calculate a standardized value for each yi.
- Multiply corresponding standardized values: (zx)i(zy)i
