Question

find the formula weight of the following substances:
A. Ammonium chloride NH4Cl B. Fe Oxide: Fe(OH)3 C. KH2PO4 D. Ammonium Sulfate (NH4)2SO4 E. Potassium Chloride KCI F. Potassium Nitrate (KNO3) find the formula weight of the following substances:
A. Ammonium chloride NH4Cl B. Fe Oxide: Fe(OH)3 C. KH2PO4 D. Ammonium Sulfate (NH4)2SO4 E. Potassium Chloride KCI F. Potassium Nitrate (KNO3) find the formula weight of the following substances:
A. Ammonium chloride NH4Cl B. Fe Oxide: Fe(OH)3 C. KH2PO4 D. Ammonium Sulfate (NH4)2SO4 E. Potassium Chloride KCI F. Potassium Nitrate (KNO3)

Explanation / Answer

A . Ammonium chloride NH4Cl

formula weight of NH4Cl = 1*14 + 4*1 + !*35.5 = 53.5

B. Formula weight of FeO = 1*56+ 1*16 =72

   formula weight of Fe(OH)3 = 1*56+3*16+3*1= 107

C formula weight of KH2PO4 = 1*39+2*1+1*31+4*16 = 136

D. formula weight of Ammonium Sulfate (NH4)2SO4 = 2*14+8*1+1*32+4*16 = 132

E. Formula weight of Potassium Chloride KCI = 1*39+1*35.5 = 74.5

F. Formula weight of Potassium Nitrate (KNO3) = 1*39+1*14+3*16 = 101
