Final answer:
The mass of 2 moles of copper (II) sulfate is 319.24 grams, calculated by multiplying 2 moles by the molar mass of CuSO₄, which is 159.62 g/mol.
Step-by-step explanation:
The student is asking about the mass of 2 moles of copper (II) sulfate, or CuSO₄. To find the mass of 2 moles of a substance, we must first determine its molar mass. The molar mass of CuSO₄ is 159.62 g/mol. To find the mass of 2 moles, we simply multiply the number of moles by the molar mass of CuSO₄:
Mass of 2 moles of CuSO₄ = 2 moles × 159.62 g/mol = 319.24 g
Therefore, the mass of 2 moles of copper (II) sulfate is 319.24 grams.
