MW = 98.08 g/mol, H2SO4 molar mass.

Calculate the Molar Mass of H2SO4

Molar Mass Calculation:

\[ \text{Molar Mass} = (2 \times \text{H}) + \text{S} + (4 \times \text{O}) \] \[ \text{Molar Mass} = (2 \times 1.008) + 32.06 + (4 \times 16.00) \] \[ \text{Molar Mass} = 98.08 \text{ g/mol} \]

Molar Mass:

1. What is Molar Mass?

Molar mass is the mass of one mole of a substance (chemical element or chemical compound). It is expressed in grams per mole (g/mol) and is calculated as the sum of the atomic masses of all atoms in the molecule.

2. How to Calculate Molar Mass

The general formula for calculating molar mass:

\[ \text{Molar Mass} = \sum (\text{Number of Atoms} \times \text{Atomic Mass}) \]

Where:

Number of Atoms — Count of each element in the molecule
Atomic Mass — Standard atomic weight of each element (from periodic table)

3. H2SO4 Molar Mass Calculation

For sulfuric acid (H₂SO₄):

\[ \text{Molar Mass} = (2 \times \text{H}) + \text{S} + (4 \times \text{O}) \] \[ \text{Molar Mass} = (2 \times 1.008) + 32.06 + (4 \times 16.00) \] \[ \text{Molar Mass} = 98.08 \text{ g/mol} \]

4. Using the Calculator

Tips: Enter the number of atoms for each element in your compound. Default values show the calculation for H₂SO₄.

5. Frequently Asked Questions (FAQ)

Q1: Why is molar mass important?
A: Molar mass is essential for stoichiometric calculations, preparing solutions, and converting between mass and moles.

Q2: What are the atomic masses used in this calculator?
A: H = 1.008 g/mol, S = 32.06 g/mol, O = 16.00 g/mol (based on IUPAC atomic weights).

Q3: How accurate is this calculation?
A: The calculation uses standard atomic weights. For precise work, use more decimal places or isotope-specific masses.

Q4: Can I calculate molar mass for any compound?
A: Yes, by entering the correct number of atoms for each element in the compound.

Q5: What's the difference between molecular weight and molar mass?
A: They are numerically identical but molar mass has units (g/mol) while molecular weight is dimensionless.
