What is Copper(II) Sulfate?

Copper(II) sulfate, or CuSO4, is an inorganic compound consisting of copper, sulfur, and oxygen. It is often encountered in its hydrated form, CuSO4·5H2O, which contains five molecules of water. This hydrated form is more commonly used due to its stability and ease of handling. The compound is known for its vibrant blue color, which makes it easily recognizable.

Calculating the Molecular Weight of CuSO4

The molecular weight of a compound is determined by summing the atomic weights of all the atoms in its formula. For CuSO4, the molecular weight can be calculated as follows:

Copper (Cu): 63.546 g/mol
Sulfur (S): 32.065 g/mol
Oxygen (O): 15.999 g/mol (since there are four oxygen atoms, multiply by 4)

Using these values, the calculation is:

Cuso4 Molecular Weight = 63.546 (Cu) + 32.065 (S) + (15.999 x 4) (O)

Cuso4 Molecular Weight = 63.546 + 32.065 + 63.996

Cuso4 Molecular Weight = 159.607 g/mol
