The molar mass is essentially the mass of one mole of a substance, expressed in grams per mole (g/mol).

To calculate it for t-butanol (C4H10O), we need to sum the atomic masses of all the atoms in its chemical formula.

Here’s a step-by-step breakdown:

1. Identify the elements and their quantities: T-butanol contains 4 carbon atoms, 10 hydrogen atoms, and 1 oxygen atom.

2. Obtain the atomic masses: Consult a periodic table or a reliable online resource like PubChem or NIST to find the atomic masses of each element:

   • Carbon (C): Approximately 12.01 amu
   • Hydrogen (H): Approximately 1.01 amu
   • Oxygen (O): Approximately 16.00 amu

3. Multiply atomic masses by the number of atoms:

   • Carbon: 4 atoms

     **12.01 amu/atom = 48.04 amu

   • Hydrogen: 10 atoms** 1.01 amu/atom = 10.10 amu
   • Oxygen: 1 atom * 16.00 amu/atom = 16.00 amu

4. Sum the results: 48.04 amu + 10.10 amu + 16.00 amu = 74.14 amu

5. Convert to molar mass: Since 1 amu is approximately equal to 1 g/mol, the molar mass of t-butanol is approximately 74.14 g/mol.

Therefore, the molar mass of t-butanol (C4H10O) is approximately 74.14 g/mol.

This value is crucial for converting between mass and moles in chemical reactions involving t-butanol.

Molecular Weight vs. Molar Mass: Clearing Up the Confusion
