The rms speed of an oxygen molecule at 0 degree Celsius is **460 m/s**.

What is rms speed of O2?

The rms speed of oxygen at room temperature is **about 500 m/s** .

How do you calculate rms speed? RMS Speed of a Molecule **v rms = v 2 – = 3 k B T m** . The rms speed is not the average or the most likely speed of molecules, as we will see in Distribution of Molecular Speeds, but it provides an easily calculated estimate of the molecules’ speed that is related to their kinetic energy.

How do you calculate the rms speed of oxygen?

- Find the absolute temperature using the Celsius to Kelvin conversion formula: T = °C + 273. T = 0 + 273. T = 273 K.
- Find molar mass in kg: From the periodic table, the molar mass of oxygen = 16 g/mol. Oxygen gas (O2) is comprised of two oxygen atoms bonded together. Therefore: …
- Find μrms: μrms = (3RT/M) ½

## What temperature is RMS velocity at O2?

**11670C**.

## What is the value of R in RMS?

It is represented by the equation: **vrms=√3RTM v r m s = 3 R T M** , where vrms is the root-mean-square of the velocity, Mm is the molar mass of the gas in kilograms per mole, R is the molar gas constant, and T is the temperature in Kelvin.

## What is the rms speed?

The root-mean-square speed is **the measure of the speed of particles in a gas**, defined as the square root of the average velocity-squared of the molecules in a gas.

## What is r in PV nRT?

PV = nRT. The factor “R” in the ideal gas law equation is known as the “**gas constant**”. R = PV. nT. The pressure times the volume of a gas divided by the number of moles and temperature of the gas is always equal to a constant number.

## Does rms speed depends on pressure?

Root mean square **velocity does not depend upon pressure**.

## Why do we use rms velocity?

The root mean square velocity is the square root of the average of the square of the velocity. As such, it has units of velocity. The reason we use the rms velocity instead of the average is that **for a typical gas sample the net velocity is zero since the particles are moving in all directions**.

## What is the most probable velocity?

The speed travelled by the number of gas particles at the same temperature is known as Most Probable Speed. Most Probable Velocity thus, can be defined as **the velocity with which the maximum number of the particles in a gas move at constant temperature**.

## Which one of the following is the most probable speed?

**The speed at the top of the curve** is called the most probable speed because the largest number of molecules have that speed. Figure 1: The Maxwell-Boltzmann distribution is shifted to higher speeds and is broadened at higher temperatures. from OpenStax.

## What is the root mean square speed of oxygen molecules at 27?

The root mean square speed of oxygen at 27°C is **760 cm s**–

## At what temp RMS velocity of O2 will be 1 3?

At what temperature, rms velocity of O_(2) molecules will be 1//3 of H_(2) molecules at -3^(@)C. or t=**480-273=207∘C**.

## At what temperature is the RMS velocity of SO2 the same as O2?

Complete answer: Hence, the temperature of the SO2 is **606K** .

## At what temperature should the hydrogen at 327?

**123oC**.
