Thus 174 protons would make at most 6 copper atoms. However, it would take 174 extra electrons (29 per atom) and even more neutrons than that to construct neutral copper atoms with stable nuclei.
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
B but im not sure if im 100% correcr
Answer:
The answer is "Upland sandpipers are primary and secondary consumers because they eat grasses and grasshoppers".
Explanation:
The limited farmland nutrition web, that reveals better which Upland sandpipers were main and secondary customers in this farmland since they eat grass with grasshoppers.

- Highlands dragonflies sometimes assemble in recently burnt fields with such a wealth of squirrels.
H2O=18.01g/mole. 210g divided by 18.01g/mole=11.653mole. 1 mole has 6.22x10^23 molecules. So there is 11.653x(6.22x10^23) molecules. Just multiply 11.653 by 6.22. Then put it as answerx10^23 molecules
