What is the ratio of effusion rates of krypton and neon at the same temperature and pressure?

The ratio of effusion rates of krypton and neon is 0.49

Explanation:

To calculate the rate of diffusion of gas, we use Graham's Law.

This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

We are given:

Molar mass of Neon = 20.18 g/mol

Molar mass of Krypton = 83.80 g/mol

By taking their ratio, we get:

Hence, the ratio of rate of effusion of krypton and neon will be 0.49

The formula we use would be the graham's law. We do as follows:

E_Kr / E_Ne = sqrt ( M_Ne / M_Kr) 

= sqrt ( 20.1797 g/mol / 83.798 g/mol ) 
= sqrt (0.24081) 
= 0.4907

Hope this answers the question. Have a nice day.

The similarity between some of the 2 terms mentioned is explained in the following section of the description.

Explanation:

In comparison to mafic rocks, which have been comparatively stronger in iron as well as magnesium, the resemblances between felsic but instead ultramafic rocks become close. Felsic corresponds to mineral deposits, magma, including rocks of silicate that are supplemented with smaller lighter particles including silicon, magnesium, gold, sodium, or potassium. Felsic magma as well as lava seems to be stronger than mafic lava throughout viscosity.
