[SOLVED] Calculating a particles most probable speed 1. The problem statement, all variables and given/known data 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 . 2. Relevant equations [tex] V_m_p = \sqrt{\frac{2*k_B*t}{m}} [/tex] 3. 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 m in kg/mol, but to no avail. I am sure this is the right equation, TFM
