Question

An ammonium carbonate sample is weighed in the laboratory. The sample weighs 22.5g. Can you determine the moles of ammonium in the sample?

Answer 1

Answer #1

1st we need to calculate moles of ammonium carbonate. (NH4)2CO3=mass/molarmass

=22.5gm/(96gm/mol)=0.2344mol

Moles of NH4= moles of (NH4)2CO3×molar ratio of NH4& (NH4)2CO3

=0.2344 moles of (NH4)2CO4×(2mole NH4/1mol (NH4)2CO3)

=0.469moles NH4
