Question

You need to prepare 10.0 mL of diluted CuSO4 solutions with the concentrations listed for Trials 1 through 4 in the table below. Before coming to lab, determine what volumes of 0.040 M CuSO4 stock solution and H2O need to be mixed together. Fill in the table with the volumes you determined. Trial Number | 0.040 M CuSO4 (mL) | H2O (mL) | Diluted Concentration (M) --- | --- | --- | --- 1 | | | 0.0050 2 | | | 0.010 3 | | | 0.020 4 | | | 0.030 5 | stock solution | 0 | 0.040

Step 1

We know that C1 is 0.040 M, V2 is 10.0 mL, and we need to find V1 for each trial. Then, we can find the volume of water needed by subtracting V1 from V2. Trial 1: C2 = 0.0050 M 0.040 M * V1 = 0.0050 M * 10.0 mL V1 = (0.0050 M * 10.0 mL) / 0.040 M = 1.25 mL H2O = Show more…
