Final answer:
The mass of one mole of copper(II) sulfate (CuSO4) is 159.62 grams.
Step-by-step explanation:
The molar mass of copper(II) sulfate (CuSO4) is calculated by adding up the atomic masses of its constituent elements. The atomic mass of copper (Cu) is 63.55 g/mol, the atomic mass of sulfur (S) is 32.07 g/mol, and the atomic mass of oxygen (O) is 16.00 g/mol. Since there are two oxygen atoms in the formula, we multiply the atomic mass of oxygen by 2. Adding these values together, we get:
Molar mass of CuSO4 = (63.55 g/mol) + (32.07 g/mol) + 2(16.00 g/mol) = 159.62 g/mol
Therefore, the mass of one mole of copper(II) sulfate is 159.62 grams.
