Calculate the molar mass of sodium acetate.

Answer

To calculate the molar mass of sodium acetate (CH₃COONa), we will follow these steps:

### Step 1: Write the chemical formula
The chemical formula for sodium acetate is CH₃COONa.

### Step 2: Identify the number of atoms of each element
In the formula CH₃COONa, we have:
- Carbon (C): 2 atoms
- Hydrogen (H): 3 atoms
- Oxygen (O): 2 atoms
- Sodium (Na): 1 atom

### Step 3: Find the atomic mass of each element
The atomic masses of the elements are approximately:
- Carbon (C): 12 g/mol
- Hydrogen (H): 1 g/mol
- Oxygen (O): 16 g/mol
- Sodium (Na): 23 g/mol

### Step 4: Calculate the total mass contributed by each element
Now, we will calculate the total mass contributed by each element in sodium acetate:
- For Carbon:
\[ 2 \text{ atoms} \times 12 \text{ g/mol} = 24 \text{ g/mol} \]
- For Hydrogen:
\[ 3 \text{ atoms} \times 1 \text{ g/mol} = 3 \text{ g/mol} \]
- For Oxygen:
\[ 2 \text{ atoms} \times 16 \text{ g/mol} = 32 \text{ g/mol} \]
- For Sodium:
\[ 1 \text{ atom} \times 23 \text{ g/mol} = 23 \text{ g/mol} \]

### Step 5: Add all the contributions together
Now, we will add all the contributions to find the molar mass of sodium acetate:
\[ \text{Total molar mass} = 24 \text{ g/mol (C)} + 3 \text{ g/mol (H)} + 32 \text{ g/mol (O)} + 23 \text{ g/mol (Na)} \]
\[ = 24 + 3 + 32 + 23 = 82 \text{ g/mol} \]

### Final Answer
The molar mass of sodium acetate is **82 g/mol**.
