Question

WHAT IS THE MOLAR MASS FOR AMMONIUM SULFIDE? A. 59.1g/mol B.82.2g/mol C.50.1g/mol

Answer 1

Answer:

68g/mol

Explanation:

The formula of ammonium sulfide is:

 Ammonium sulfide  = (NH₄)₂S

 The molar mass of a compound is the mass in gram of one mole of the substance. In a compound, it is expressed gram formula mass or gram-molecular weight.

 It is determined by the addition of the component atomic masses and then expressed in grams;

     Atomic mass of N = 14, H  = 1 and S = 32

 (NH₄)₂S  = 2[14 + 4(1)] + 32  = 36 + 32  = 68g/mol
