$2.20\ \text{g}$ of ethanal ($44.05\ \text{g/mol}$) is used in two separate experiments. In the first, all of it is warmed with excess Tollens' reagent. In the second, the same mass is warmed with excess Fehling's solution. Tollens' reagent gives $2$ mol of silver ($107.87\ \text{g/mol}$) for each mole of aldehyde. Fehling's solution gives $1$ mol of copper(I) oxide ($143.09\ \text{g/mol}$). Find the amount of ethanal in the sample. Then find the mass of silver from the first experiment, and the mass of copper(I) oxide from the second.
