Question

the chemical formula for t - butanol is: \\((\text{ch}_3)_3\text{coh}\\) calculate the molar mass of t - butanol. round your answer to 2 decimal places. \\(\square\\ \text{g}\cdot\text{mol}^{-1}\\)

Explanation:

Step1: Determine atomic masses

Carbon (C): $12.01\ \text{g/mol}$, Hydrogen (H): $1.008\ \text{g/mol}$, Oxygen (O): $16.00\ \text{g/mol}$.

Step2: Count atoms in \((CH_3)_3COH\)

• C: 4 (3 from \((CH_3)_3\) + 1 from \(COH\))
• H: 10 (3×3 from \((CH_3)_3\) + 1 from \(COH\))
• O: 1
• H: Wait, \((CH_3)_3\) has 3 groups of \(CH_3\), so H is \(3×3 = 9\), plus 1 from \(OH\), total H: 10. C: 3 + 1 = 4. O: 1.

Step3: Calculate molar mass

Molar mass = (4×12.01) + (10×1.008) + (1×16.00)
= \(48.04 + 10.08 + 16.00\)
= \(74.12\ \text{g/mol}\)

Answer:

74.12
