Ammonium chloride, nh4cl, is a very soluble salt in water. draw the lewis structures of the ammonium and chloride ions

Lewis Structures of Ammonium Ion (RED) and Chloride Ions (BLUE) are attached below.

Lewis structures are those structures which shows the environment of electrons in a molecule. These structures basically depicts the bonding electrons and non-bonding electrons also known as Lone pair electrons.

In attached structure it can be seen that the ammonium ion is made when nitrogen atom is forming four single bonds with four hydrogen atoms and the formal charge on nitrogen becomes +1. While, in case of chloride ion the chlorine atom has four lone pair of electrons and has a formal charge of -1.

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.
