How to find average molecular weight?
Understand the Problem
The question is asking for the methodology to calculate the average molecular weight, which involves summing the weights of the different isotopes of an element and dividing by their total abundance. This is a typical chemistry calculation.
Answer
Measure the molecular weight of n molecules, sum the weights, and divide by n.
The final answer is to measure the molecular weight of n molecules, sum the weights, and divide by n.
Answer for screen readers
The final answer is to measure the molecular weight of n molecules, sum the weights, and divide by n.
More Information
The average molecular weight is a basic measure used in chemistry to describe the overall mass of molecules within a sample. This technique is particularly useful in polymer chemistry to understand the distribution of different molecular sizes in a sample.
Tips
Common mistakes include miscounting the total number of molecules or using incorrect molecular weights.
