The molar mass of C4H10, which is commonly known as butane, can be calculated by adding together the atomic masses of its constituent atoms.
Butane consists of 4 carbon (C) atoms and 10 hydrogen (H) atoms. The atomic mass of carbon is approximately 12.01 g/mol, and the atomic mass of hydrogen is about 1.008 g/mol.
To find the total molar mass of butane, we can use the formula:
Molar Mass = (Number of Carbon Atoms × Atomic Mass of Carbon) + (Number of Hydrogen Atoms × Atomic Mass of Hydrogen)
Substituting the values:
- For Carbon: 4 × 12.01 g/mol = 48.04 g/mol
- For Hydrogen: 10 × 1.008 g/mol = 10.08 g/mol
Now, we add these two results together:
Molar Mass = 48.04 g/mol + 10.08 g/mol = 58.12 g/mol
Therefore, the molar mass of C4H10 is approximately 58.12 g/mol.
