What is the chemical formula for ammonium sulfate? nhmc022-1.jpg(somc022-2.jpg) nhmc022-3.jpg(so4)mc022-4.jpg (nhmc022-5.jpg)mc022-6.jpgsomc022-7 .jpg (nhmc022-8.jpg)mc022-9.jpgso4

The chemical formula for this compound is

Explanation:

Ammonium ions and sulfate ions are the polyatomic ions having charges +1 and -2 respectively.

Polyatomic ions are defined as the ions which contains more than 2 atoms.

Criss cross method is the method used for the writing chemical formula of  compounds in which the exchange of valencies of the ions is done which are then written in the form of subscripts of the formula.

Hence, the chemical formula for this compound is

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.
