Question

calculate the atomic mass of element X, if it has 2 naturally occurring isotopes with the following masses and natural abundance:X-4544.8776amu 32.88% X-4746.9443amu67.12%​

Answer 1

Hey there!

To find this, you should:

1) multiply the percentage (but in a decimal form) of each isotope by the mass.
2) add all your masses together
3) make sure to check for significant figures and you’re done!

Hope this helps :)
