What is most probable speed? Using the expression of the number of mol

Question

What is most probable speed? Using the expression of the number of molecules in a Maxwellian gas in the range v to v + dv as
$$dN_v = 4\pi N \left( \frac{m}{2\pi k_BT} \right)^{3/2} v^2 \exp \left[ - \left( \frac{mv^2}{2k_BT} \right) \right] dv$ $

In thermal physics and statistical mechanics, the most probable speed of molecules in a gas is the speed at which the maximum number of molecules is moving. For a gas in thermal equilibrium, the distribution of molecular speeds is given by the Maxwell-Boltzmann distribution.
