Calculate the root main Square Velocity for the atoms in a sample of Nitrogen gas (N2) at 25°c of CO₂ and SO₂ from the same container and at the same temperature and pressure.
Answer:
To calculate the root mean square velocity of atoms in a gas, we need to know the mass of the atoms, the temperature of the gas, and the gas constant. The root mean square velocity can be calculated using the following equation:
v_rms = sqrt((3RT)/m)
Where v_rms is the root mean square velocity, R is the gas constant, T is the temperature in kelvins, and m is the mass of the atoms in kilograms.
For nitrogen gas (N2), the mass of each atom is 14/6.022 x 10^23 = 2.34 x 10^-23 kg.
For CO2, the mass of each atom is 12/6.022 x 10^23 = 2.0 x 10^-23 kg.
For SO2, the mass of each atom is 32/6.022 x 10^23 = 5.3 x 10^-23 kg.
Plugging these values into the equation, we can calculate the root mean square velocity for each gas at 25°C:
v_rms (N2) = sqrt((38.31298)/(2.34 x 10^-23)) = 466 m/s
v_rms (CO2) = sqrt((38.31298)/(2.0 x 10^-23)) = 505 m/s
v_rms (SO2) = sqrt((38.31298)/(5.3 x 10^-23)) = 691 m/s
Therefore, the root mean square velocity of atoms in a sample of Nitrogen gas at 25°C is 466 m/s, while the root mean square velocity of atoms in a sample of CO2 at the same temperature and pressure is 505 m/s, and the root mean square velocity of atoms in a sample of SO2 at the same temperature and pressure is 691 m/s.

cl-35, and cl-38. cl-35 makes up 28 percent and cl-37 makes up 72 percent. the atomic mass of cl-35 is 35 amu, and the stomic mass of cl-38 is 38 amu.
The average atomic mass of Cl 35 and Cl 37 is 35.5. Atomic mass is the amount of matter that makes up an atom.
What is atomic mass, for instance?A mass corresponding to one-twelfth of an atom of carbon-12 is referred to as an atomic mass unit. Any isotope of any element's mass is represented in proportion to the standard carbon-12. For instance, the mass of one helium-4 atom is 4.0026 amu. Sulfur-32 atoms have a mass of 31.972 amu.
How is the definition of atomic mass determined?The average mass of an element's atoms expressed in atomic mass units is the term "atomic mass" for an element (amu, also known as daltons, D). The mass of each isotope of that element is multiplied by its abundance to produce the atomic mass, which is a weighted average of all its isotopes.
