Starting from the primary standard solution in Question 4 and using the dilution scheme in Figure 1, calculate the concentrations of Standards #1-5. Show all work on a piece of scratch paper. Label each calculation clearly (Standard #1, Standard #2, etc) and circle your final answer for each standard. Be sure to round your answers to the correct number of significant figures and include units. Molarity in #4 is 0.0004089 M or 4.089x10^-4

This image illustrates a serial dilution process using volumetric flasks. The process involves the following steps: 1. **Flask 1: Primary Standard** - Contains 0.02 g of FD&C 40 dye. - 100 mL Volumetric Flask used to create the primary standard solution. 2. **Flask 2: Standard #1** - 1:10 dilution is made from the primary standard. - Volumetric Flask is used to prepare the first standard dilution. 3. **Flask 3: 25 mL Volumetric Flask** - Further dilution is performed from Flask 2. 4. **Flask 4: 25 mL Volumetric Flask** - Continuation of the dilution series from Flask 3. 5. **Flask 5: 25 mL Volumetric Flask** - Continuation of the dilution series from Flask 4. 6. **Flask 6: 25 mL Volumetric Flask** - Final in the series of dilutions from Flask 5. The diagram also shows the use of appropriate pipets to transfer solutions between flasks, maintaining accuracy in the dilution factors. Each flask progressively dilutes the concentration from its predecessor.
