What is the molar mass of (NH4)2S

Anastaziya [24]

Answer:

This compound is Ammonium Sulphide and has molar mass 68 g/mol.

Explanation:

Molar Mass : It is the mass of 1 mole of the substance and in grams.Its units are gram/mole.

It is numerically equal to mass of the substance in atomic mass units

How to calculate Molar mass :

$(NH_{4})_{2}S = 2(atomic\ mass\ of\ N + 4\times mass\ of\ H ) +atomic\ mass\ of\ S$

$(NH_{4})_{2}S = 2(14 + 4(1) ) + 32$

$(NH_{4})_{2}S = 2(14 + 4 ) + 32$

$(NH_{4})_{2}S = 2(18) + 32$

$(NH_{4})_{2}S = 36 + 32$

$(NH_{4})_{2}S = 68$ grams/mole

Molar mass of Ammonium sulphide is 68 g/mol
