Answer:
3.36 M
Explanation:
Step 1: Given data
- Mass of CuSO₄.6H₂O (m): 25.2 g
- Molar mass of CuSO₄.6H₂O (M): 267.72 g/mol
- Volume of solution (V): 28.0 mL (we will assume it is equal to the volume of water)
Step 2: Calculate the moles (n) of CuSO₄.6H₂O (solute)
We will use the following expression.
n = m/M
n = 25.2 g / (267.72 g/mol) = 0.0941 mol
Step 3: Calculate the molarity
Molarity is equal to the moles of solute divided by the liters of solution.
M = 0.0941 mol/0.0280 L = 3.36 M
