Calculate :
Mass in gram of 5.8 mol `N_(2)O`

Answer

To calculate the mass in grams of 5.8 moles of \( N_2O \), we can follow these steps:

### Step 1: Determine the molar mass of \( N_2O \)
To find the molar mass, we need to add the atomic masses of nitrogen (N) and oxygen (O):
- The atomic mass of nitrogen (N) is approximately 14 g/mol.
- The atomic mass of oxygen (O) is approximately 16 g/mol.

Since there are 2 nitrogen atoms and 1 oxygen atom in \( N_2O \):
\[ \text{Molar mass of } N_2O = (2 \times 14 \, \text{g/mol}) + (1 \times 16 \, \text{g/mol}) \]
\[ = 28 \, \text{g/mol} + 16 \, \text{g/mol} = 44 \, \text{g/mol} \]

### Step 2: Calculate the mass of 5.8 moles of \( N_2O \)
Now that we know the molar mass of \( N_2O \) is 44 g/mol, we can calculate the mass of 5.8 moles:
\[ \text{Mass} = \text{Number of moles} \times \text{Molar mass} \]
\[ \text{Mass} = 5.8 \, \text{moles} \times 44 \, \text{g/mol} \]
\[ = 255.2 \, \text{grams} \]

### Final Answer
The mass of 5.8 moles of \( N_2O \) is **255.2 grams**.
