In this article, we will delve into the specifics of CuSO4, examining its structure, properties, and applications, while also shedding light on its molar mass. By the end, you will have a comprehensive understanding of CuSO4 and why its molar mass is a vital piece of information in the field of chemistry.

What is CuSO4 and Its Composition?

CuSO4, or Copper(II) sulfate, is an inorganic compound that consists of copper, sulfur, and oxygen. It is commonly encountered in its pentahydrate form (CuSO4·5H2O), which is a blue crystal known for its vibrant color and solubility in water. However, for our purposes, we will focus on the anhydrous form of CuSO4.

How is the Molar Mass of CuSO4 Calculated?

To calculate the molar mass of CuSO4, one must consider the atomic masses of each element present in the compound. The molar mass is determined by adding the atomic masses of copper (Cu), sulfur (S), and oxygen (O) in the appropriate quantities:

Atomic mass of Cu: 63.55 g/mol
Atomic mass of S: 32.07 g/mol
Atomic mass of O: 16.00 g/mol (and there are 4 oxygen atoms)

Using this information, the molar mass of CuSO4 can be calculated as follows:

Molar mass of CuSO4 = (1 × 63.55) + (1 × 32.07) + (4 × 16.00) = 63.55 + 32.07 + 64.00 = 159.62 g/mol
