Today we conducted an experiment to identify the average atomic mass of a newly discovered element, beanium. To identify the atomic mass, the first step was to count up all the beans in the sample as well as how many there were in each type of bean. This information allowed us to calculate the average atomic mass by multiplying each isotope by its mass abundance and adding them together. [(mass)(% abundance)]+[(mass)(%abundance)]= average atomic mass
Your post is really good in that you briefly describe the lab we did in class but also included the formula for what we were solving. I think next time you could try spacing your post out a little so it is easier to distinguish between the lab information and the formula for what you were calculating. Also, this is an easy post to get one of your pictures in just by taking a picture of the beans we used in class!
ReplyDeleteErin, I liked how you showed the connection between our lab and the average atomic mass of an atom. Your briefly summed up the beanium lab and gave anyone reading enough background information on the procedure. However, next time maybe explain what the average atomic mass is of an atom is. Also, you could show a practice problem using the equation. Readers will then be able to fully understand what the average atomic mass is and how to solve it by seeing it found step by step. Other than that, great post!
