To find out how many moles of copper (II) sulfate are present in a 100 cm³ solution, we need additional information. Specifically, we need the concentration of the copper (II) sulfate solution.
Step-by-step approach:
Understand the molarity concept:
Molarity (M) is the number of moles of solute per liter of solution. It is calculated by the formula: M = liters of solution moles of solute
Convert volume from cm³ to liters:
Since molarity uses liters, convert the 100 cm³ to liters. 100 cm 3 = 0.100 L
Use the molarity if available:
If you have the molarity of the copper (II) sulfate solution, you can use the formula to find the moles.
For example, if the molarity is 0.5 M, then: moles of copper (II) sulfate = M × Volume in liters = 0.5 × 0.100 = 0.050 moles
Conclusion:
Without the molarity, it's not possible to calculate the moles of copper (II) sulfate.
To accurately determine the moles, you need the concentration of the solution.
