To calculate the molar mass of propane (C₃H₈), you can sum the molar masses of its constituent atoms:
- Carbon (C): 12.01 g/mol
- Hydrogen (H): 1.01 g/mol
For C₃H₈:
- There are 3 carbon atoms: \(3 \times 12.01 \, \text{g/mol} = 36.03 \, \text{g/mol}\)
- There are 8 hydrogen atoms: \(8 \times 1.01 \, \text{g/mol} = 8.08 \, \text{g/mol}\)
Now, add these two values together:
\[ 36.03 \, \text{g/mol} + 8.08 \, \text{g/mol} = 44.11 \, \text{g/mol} \]
Rounding this to the nearest whole number gives you approximately 44 g/mol.
Thus, the correct answer is:
**44 g**
- Carbon (C): 12.01 g/mol
- Hydrogen (H): 1.01 g/mol
For C₃H₈:
- There are 3 carbon atoms: \(3 \times 12.01 \, \text{g/mol} = 36.03 \, \text{g/mol}\)
- There are 8 hydrogen atoms: \(8 \times 1.01 \, \text{g/mol} = 8.08 \, \text{g/mol}\)
Now, add these two values together:
\[ 36.03 \, \text{g/mol} + 8.08 \, \text{g/mol} = 44.11 \, \text{g/mol} \]
Rounding this to the nearest whole number gives you approximately 44 g/mol.
Thus, the correct answer is:
**44 g**
