What is the correct equation for calculating the average atomic mass for 3 isotopes? (pls be 100%of your answer pls no guessing)
Add all the masses together and divide by 3
Add all the protons together and divide by three
Multiply the percent abundance by each mass, add them up, and then divide by 3 Multiply the percent abudance by each mass and add them up

Respuesta :

Answer:

The correct equation for measuring the average microscopic weight  for 3 isotopes is multiply the rate of abundance by each weight and add them.

Explanation:

To calculate the average microscopic mass of element using weights and relative abundance we have to follow the following steps.

  • Take the correct weight of each isotope (that will be in decimal form)
  • Multiply the weight of each isotope by its abundance
  • Add each of the results together.

This gives the required  average microscopic weight of the three isotopes.
