Question: A polymerization process produced a Gaussian distribution of polymers in the sense that the proportion of molecules having a molar mass in the range M

A polymerization process produced a Gaussian distribution of polymers in the sense that the proportion of molecules having a molar mass in the range M to M + dM was proportional to e-(M-M)2/2YdM. What is the number average molar mass when the distribution is narrow?
