Calculate the molar mass of `H_2SO_4`

Answer

To calculate the molar mass of sulfuric acid (H₂SO₄), we will follow these steps:

### Step 1: Identify the number of each type of atom in the compound.
In H₂SO₄:
- There are 2 hydrogen (H) atoms.
- There is 1 sulfur (S) atom.
- There are 4 oxygen (O) atoms.

### Step 2: Find the atomic mass of each element.
- The atomic mass of hydrogen (H) is approximately 1 g/mol.
- The atomic mass of sulfur (S) is approximately 32 g/mol.
- The atomic mass of oxygen (O) is approximately 16 g/mol.

### Step 3: Calculate the total mass contributed by each type of atom.
- For hydrogen:
\[ 2 \text{ (H atoms)} \times 1 \text{ g/mol} = 2 \text{ g/mol} \]
- For sulfur:
\[ 1 \text{ (S atom)} \times 32 \text{ g/mol} = 32 \text{ g/mol} \]
- For oxygen:
\[ 4 \text{ (O atoms)} \times 16 \text{ g/mol} = 64 \text{ g/mol} \]

### Step 4: Add the total masses together to find the molar mass of H₂SO₄.
\[ \text{Total molar mass} = 2 \text{ g/mol (H)} + 32 \text{ g/mol (S)} + 64 \text{ g/mol (O)} \]
\[ = 2 + 32 + 64 = 98 \text{ g/mol} \]

### Final Answer:
The molar mass of H₂SO₄ is **98 g/mol**.
