What is the theoretical yield, in g, of ethanamide, \( CH_{3}CONH_{2} \), that can be produced from the reaction of 4.00 g of ammonium carbonate, \( (NH_{4})_{2}CO_{3} \), with excess ethanoic acid, \( CH_{3}COOH \)?
\( CH_{3}COOH(l)+(NH_{4})_{2}CO_{3}(s)\rightarrow 2CH_{3}COONH_{4}(aq)+H_{2}O(l)+CO_{2}(g) \)
\( CH_{3}COONH_{4}(aq)\rightarrow CH_{3}CONH_{2}(s)+H_{2}O(l) \)
\( M_{r}(NH_{4})_{2}CO_{3}=96.11 \)
\( M_{r}CH_{3}CONH_{2}=59.08 \)
