Give the formula and calculate the molar mass for each of the following substances.

ammonium sulfide

dichlorophenol, C6H4OCl2

barium hydride

potassium dihydrogen phosphate

Expert Solution

Ammonium Sulphide : NH4S

Molar mass = 14.01 gm/mol *1 + 4 * 1gm/mol + 1*32.06gm/mol = 50.10 gm/mol

-----------------------------------------------------

C6H4OCl2

Molar mass : 6*12.01 gm/mol + 4*1.01gm/mol + 1*16gm/mol * 2*35.5gm/mol = 171.06 gm/mol

-----------------------------------------

Barium Hydride : BaH2

Molar mass : 1*137.33gm/mol + 2* 1.01gm/mol = 139.34 gm/mol

---------------------------------

Potassium Hydrogen phosphate

KHPO4

Molar mass : 1* 39.10 gm/mol +1*1.01 gm/mol + 1*30.97 gm/mol + 4* 16 gm/mol = 135.08 gm/mol
