Answer:
Mass = 1.76 g
Explanation:
Given data:
Volume of solution = 25 mL
Molarity = 0.45 M
Amount of CuSO₄.5H₂O = ?
Solution:
Molarity = number of moles / volume in litter
Number of moles = Molarity × Volume in L
Number of moles = 0.45 M × 0.025 L
Number of moles = 0.011 mol
Mass of f CuSO₄.5H₂O:
Mass = Number of moles × molar mass
Mass = 0.011 mol × 159.6 g/mol
Mass = 1.76 g
