1. What is Molar Mass?

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). For compounds, it's the sum of the atomic masses of all atoms in the molecule.

2. How is CuSO4 Molar Mass Calculated?

The molar mass of copper(II) sulfate (CuSO₄) is calculated as:

\[ \text{Molar Mass} = \text{Cu} + \text{S} + 4 \times \text{O} \]

Where:

Cu — Copper (63.546 g/mol)
S — Sulfur (32.065 g/mol)
O — Oxygen (15.999 g/mol)

Calculation: 63.546 (Cu) + 32.065 (S) + 4 × 15.999 (O) = 159.609 g/mol

3. Importance of Molar Mass

Details: Molar mass is essential for stoichiometric calculations, solution preparation, and converting between grams and moles in chemical reactions.

4. Using the Calculator

Tips: This calculator uses standard atomic weights. For precise work, use isotope-specific masses or measured values.

5. Frequently Asked Questions (FAQ)

Q1: Why is the molar mass 159.609 g/mol?
A: This is the sum of the atomic masses of one copper atom (63.546), one sulfur atom (32.065), and four oxygen atoms (4 × 15.999).

Q2: Does this include water of crystallization?
A: No, this is for anhydrous CuSO₄. The pentahydrate (CuSO₄·5H₂O) has additional mass from water molecules.

Q3: Are there variations in atomic weights?
A: Yes, IUPAC updates standard atomic weights periodically. This calculator uses commonly accepted values.

Q4: How accurate is this calculation?
A: For most practical purposes, it's sufficiently accurate. For precise work, consider isotopic composition.

Q5: Can I calculate molar mass for other compounds?
A: Yes, using the same principle - sum the atomic masses of all atoms in the molecule.
