Understanding Molecular Mass
Molecular mass, also known as molecular weight, is the sum of the atomic masses of all atoms in a molecule. To calculate the molecular mass of a substance containing 4 carbon atoms and 10 hydrogen atoms, we need to know the atomic masses of carbon and hydrogen.
Atomic Masses
- Carbon (C): Approximately 12.01 g/mol
- Hydrogen (H): Approximately 1.008 g/mol
Calculating the Molecular Mass
To find the molecular mass, follow these steps:
1. Calculate the total mass of carbon:
- Number of carbon atoms = 4
- Molecular mass from carbon = 4 atoms × 12.01 g/mol = 48.04 g/mol
2. Calculate the total mass of hydrogen:
- Number of hydrogen atoms = 10
- Molecular mass from hydrogen = 10 atoms × 1.008 g/mol = 10.08 g/mol
3. Sum the total molecular mass:
- Total molecular mass = Mass from carbon + Mass from hydrogen
- Total molecular mass = 48.04 g/mol + 10.08 g/mol = 58.12 g/mol
Final Result
The molecular mass of the substance that contains four atoms of carbon and ten atoms of hydrogen is 58.12 g/mol. This value indicates the mass of one mole of the substance and is crucial in determining its behavior in chemical reactions and stoichiometry.
