What is the mass of one atom of Calciumin atomic mass units?

Isotopes are atoms of same element with different mass number. Select one: O True False

Calculate mono isotopic mass and average mass of C8H10N4O2 show your work

I'm sturggling on the last question part c. I submitted what I though was correct (36 on top and  78 on bottom with the symbol Kr) if that makes sense. I was wondering if you could help me. Thank you. I have 10 attemps and already used 3 because I miss read the question at first and only submitted symbols instead of the atomic number and mass number as well like you see on a periodic table.
