Calculate the mass of one mole of (NH4)2CO3​

96.09 g/mol

Explanation:

O>16.0,N>14.0,C>12.0,H>1.0

E.G:{2 * 14.0} +{8 * 1.0}+12.0+{16.0 * 3}

=28.0+8.0+12.0+48.0

=96.0g

Ammonium carbonate is a salt with the chemical formula (NH₄)₂CO₃. Since it readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt.
