What is the atomic mass of an element that has 37 protons, 43 neutrons, and 36 electrons?

Atomic Mass 85.4678 atomic mass units

Number of Protons 37

Number of Neutrons 48

Number of Electrons 37

Explanation:

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

the answers would be

the first one and the second one
