The atomic mass of copper (Cu) is 63.546 amu, the atomic mass of sulfur (S) is 32.065, and the atomic mass of oxygen (O) is 15.999 amu. Which molar mass is correct for copper sulfate (CuSO4)?(1 point) Responses 159.607 g/mol 159.607 g/mol 225.802 g/mol 225.802 g/mol 111.610 g/mol 111.610 g/mol 446.440 g/mol 446.440 g/mol
The correct molar mass of copper sulfate (CuSO4) is calculated as follows:
1 atom of Cu = 63.546 amu
1 atom of S = 32.065 amu
4 atoms of O = 4 x 15.999 amu = 63.996 amu
Total molar mass of CuSO4 = 63.546 + 32.065 + 63.996 = 159.607 g/mol
Therefore, the correct molar mass for copper sulfate (CuSO4) is 159.607 g/mol.
