**[SOLVED] Calculating a particles most probable speed**

## Homework Statement

Diatomic carbon dioxide gas (CO2) has molar mass of 44.0 g/mol is at a temperature of 281 Kelvin.

Calculate the most probable speed .

## Homework Equations

[tex] V_m_p = \sqrt{\frac{2*k_B*t}{m}} [/tex]

## The Attempt at a Solution

[tex] V_m_p = \sqrt{\frac{2*(1.3807*10^-^2^3)*281}{44}} [/tex]

I have also tried with

[tex] V_m_p = \sqrt{\frac{2*(1.3807*10^-^2^3)*281}{0.044}} [/tex]

with

**in kg/mol, but to no avail. I am sure this is the right equation,**
