Final answer:
To calculate the molar mass of t-butanol (tert-butyl alcohol), you add up the atomic masses of its constituent atoms: 4 carbon atoms, 10 hydrogen atoms, and 1 oxygen atom, giving a total of 74.12 g/mol.
Step-by-step explanation:
Calculating the Molar Mass of t-Butanol
The molar mass of a compound is the mass in grams of one mole of that compound. To calculate the molar mass of t-butanol, which is also known as tert-butyl alcohol, you need to know its chemical formula, which is C4H9OH. You would then add up the atomic masses of all the atoms in the formula: 4 carbon atoms (C), 10 hydrogen atoms (H), and 1 oxygen atom (O). Using the periodic table, the atomic masses are approximately 12.01 g/mol for carbon, 1.008 g/mol for hydrogen, and 16.00 g/mol for oxygen.
Therefore, the calculation would look like this:
- Carbon: 4 atoms × 12.01 g/mol = 48.04 g/mol
- Hydrogen: 10 atoms x 1.008 g/mol = 10.08 g/mol
- Oxygen: 1 atom x 16.00 g/mol = 16.00 g/mol
Adding these together, the molar mass of t-butanol is:
48.04 g/mol + 10.08 g/mol + 16.00 g/mol = 74.12 g/mol
