[ar]4s23d104p3 is the electron configuration of a(n) atom.

The given configuration is of Arsenic atom.

Explanation:

Electronic configuration tells us about the number of electrons that are present in an atom. It also determines the atomic number of an element.

For the given configuration:  

Number of electrons present in argon = 18

So, total number of electrons in the given configuration = 18 + 2 + 10 + 3 = 33

The element having atomic number '33' is Arsenic.

Hence, the given configuration is of Arsenic atom.

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 dissolution of polymer can be thermodynamically described in 2 steps.
