Final answer:

Without a balanced chemical equation and molar ratios, it is impossible to calculate the amount of silver nitrate that would be left over after reacting with sodium bicarbonate.

Step-by-step explanation:

To determine how many grams of silver nitrate are left after it reacts with sodium bicarbonate, we need to know the stoichiometry of the reaction. However, the student's question mentioned sodium bicarbonate reacting with silver nitrate, for which there isn't a direct reaction. If we assume the student meant to refer to the reaction between sodium chloride and silver nitrate, which forms silver chloride (AgCl) as a precipitate, then we can calculate the amount of silver nitrate remaining using stoichiometry. But since the question does not provide enough information about the reaction and does not involve a chemical equation or molar ratios, we cannot calculate the amount of silver nitrate that would be left over without making assumptions about the reaction that are not presented in the question.
