The atomic mass of Europium is 152 amu
Work:
151(0.4803) = 72.52 amu
153(0.5197) = 79.5 amu
72.5 + 79.5 = 152 amu
The correct answer is c. Please give me brainlest let me know if it’s correct or not thanks bye
The mass of nucleons (and thus of the nucleus) is roughly 1000 times greater than that of electrons.
Don’t really understand what you’re asking but, if you’re asking how to read a graduated cylinder:
