## 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 is the value of NTP?

NIST uses a temperature of 20 °C (293.15 K, 68 °F) and an absolute pressure of 1 atm (14.696 psi, 101.325 kPa). This standard is also called normal temperature and pressure (abbreviated as NTP).

## Is NTP and STP same?

STP stands for Standard Temperature and Pressure. NTP stands for Normal Temperature and Pressure. STP is set by the IUPAC as 0°C and 100 kPa or 1 bar. NTP is set at 101.325 kPa but uses 20°C as the temperature.

## What does STP stand for?

Standard Temperature and Pressure

## How is NTP volume calculated?

It is also known that volume occupied by 1 mole of gas at NTP is 22.4 L. Substituting P=1 atm, T=293 K, R=0.0821 L atm K−1 mol−1, we get V=24.05 L as the molar volume.
