In the laboratory, 3.43 grams of CuSO4-5H20 is measured and used to prepare a 50.00 mL solution. What is the concentration of the prepared solution?
Answers
Explanation:
The mass of water in a 250 ml beaker is 248.78 g. If the temperature in the lab is 18°C, what is the volume of water in the beaker? 2. The laboratory procedure calls for 50.00 mL of CuSO4 solution with a concentration of 0.300 M. What mass of CuSO4.5H20 is required to prepare this solution? 3. In the laboratory, 3.43 grams of CuSO4-5H2O is measured and used to prepare a 50.00 mL solution. What is the concentration of the prepared solution? 4. The laboratory procedure calls for 50.00 mL of Na2CO3 solution with a concentration of 0.500 M. What mass of Na2CO3 is required to prepare this solution? A stock solution with a concentration of 0.300 M is used to prepare five serial dilutions with a dilution factor of 10. Use the schematic provide in Figure 2.5 to complete Questions 5 to 1. 5. Solution A is prepared using a stock solution with a concentration of 0.300 M by a dilution factor of 10. What is the concentration of Solution A? 6. What volume of stock solution is required to prepare 10.0 mL of Solution A? 7. What volume of distilled water is required to prepare 10.0 mL of Solution A? 8. Calculate the theoretical yield of copper carbonate when 20.0 mL of 0.300 M copper (II) sulphate reacts with 20.0 mL of 0.500 M sodium carbonate Cusacaq) + Na2CO3(aq) + CUCO3(8) + Na, S04(aq)
