The question requires us to calculate the mass of anhydrous copper sulfate, CuSO4.
To calculate the molar mass of a compound, we need to take into consideration the atomic masses of the elements that are in the molecule and the number of atoms of each element.
For anhydrous copper sulfate, there are 1 atom of copper (Cu), 1 atom of sulfur (S) and 4 atoms of oxygen (O).
The atomic masses we need to consider are:
atomic mass of Cu = 63.546 u
atomic mass of S = 32.065 u
atomic mass of O = 15.999 u
Next, we calculate the molar mass:
molar mass (CuSO4) = (1 * 63.546) + (1 * 32.065) + (4 * 15.999) = 159.61 g/mol
Therefore, the molar mass of anhydrous copper sulfate is 159.61 g/mol.
