Most Probable Speed Solution

STEP 0: Pre-Calculation Summary

Formula Used

Most Probable Speed = sqrt((2*[R]*Temperature of Gas A)/Molar Mass)
V_p = sqrt((2*[R]*T_ga)/M_molar)
This formula uses 1 Constants, 1 Functions, 3 Variables

Constants Used

[R] - Universal gas constant Value Taken As 8.31446261815324

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Most Probable Speed - (Measured in Meter per Second) - Most probable speed is the speed at the top of Maxwell-Boltzmann Distribution curve because the largest number of molecules have that speed.
Temperature of Gas A - (Measured in Kelvin) - The temperature of Gas A is the measure of hotness or coldness of gas A.
Molar Mass - (Measured in Kilogram Per Mole) - Molar Mass is the mass of a given substance divided by the amount of substance.

STEP 1: Convert Input(s) to Base Unit

Temperature of Gas A: 45 Kelvin --> 45 Kelvin No Conversion Required
Molar Mass: 44.01 Gram Per Mole --> 0.04401 Kilogram Per Mole (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_p = sqrt((2*[R]*T_ga)/M_molar) --> sqrt((2*[R]*45)/0.04401)

Evaluating ... ...

V_p = 130.395517711186

STEP 3: Convert Result to Output's Unit

130.395517711186 Meter per Second --> No Conversion Required

FINAL ANSWER

130.395517711186 ≈ 130.3955 Meter per Second <-- Most Probable Speed

Average Speed of Gases

Go Average Speed of Gas = sqrt((8*[R]*Temperature of Gas A)/(pi*Molar Mass))

Molar Mass of Gas given Average Speed of Gas

Go Molar Mass = (8*[R]*Temperature of Gas A)/(pi*Average Speed of Gas^2)

Degree of Freedom given Equipartition Energy

Go Degree of Freedom = 2*Equipartition Energy/([BoltZ]*Temperature of Gas B)

Absolute Humidity

Go Absolute Humidity = Weight/Volume of Gas
