Final answer:
The molar mass of t-butanol is calculated by adding the atomic masses of its constituent atoms, resulting in a molar mass of 74.14 g/mol.
Step-by-step explanation:
The molar mass of t-butanol, which has the chemical formula (CH3)3COH, is calculated by adding the atomic masses of all the atoms in the molecule. The molar mass of carbon (C) is approximately 12.01 g/mol, hydrogen (H) is about 1.01 g/mol, and oxygen (O) is approximately 16.00 g/mol. The molecule has 4 carbon atoms, 10 hydrogen atoms, and 1 oxygen atom.
The calculation is as follows:
- 4 C atoms × 12.01 g/mol = 48.04 g/mol
- 10 H atoms × 1.01 g/mol = 10.10 g/mol
- 1 O atom × 16.00 g/mol = 16.00 g/mol
Adding these together gives us
48.04 g/mol + 10.10 g/mol + 16.00 g/mol = 74.14 g/mol
Therefore, the molar mass of t-butanol is 74.14 g/mol.
