**Table of Reagents:**

Complete the following table of reagents (you may need to look up some information: I recommend the Sigma-Aldrich catalog/website as a useful source). Use the appropriate number of significant figures.

| Compound                          | Mass (g) | Molar mass (g/mol) | Moles       |
|-----------------------------------|----------|---------------------|-------------|
| 4-tert-butylcyclohexanone         | 0.60     | 156.425             | 3.84 x 10^-3 |
| Sodium borohydride                | 0.10     | 37.83               | 2.64 x 10^-3 |
| 4-tert-butylcyclohexanol          | 1.32     | 156.27              | 8.45 x 10^-3 |

**Questions:**

1. **Which is the limiting reagent?**

2. **Calculate the % yield of 4-tert-butylcyclohexanol (show working and note significant figures).**

---

**Explanation of the Table:**

The table contains information about three compounds involved in a chemical reaction. Each compound's mass in grams and their respective molar masses in g/mol are provided. Based on these values, the number of moles involved in the reaction is calculated.

- **4-tert-butylcyclohexanone** is used in a quantity of 0.60 grams with a molar mass of 156.425 g/mol, resulting in 3.84 x 10^-3 moles.
- **Sodium borohydride** is present as 0.10 grams with a molar mass of 37.83 g/mol, giving 2.64 x 10^-3 moles.
- The final product, **4-tert-butylcyclohexanol**, has a mass of 1.32 grams and a molar mass of 156.27 g/mol, equating to 8.45 x 10^-3 moles.

The questions prompt calculation of the limiting reagent, which is the reactant that will be completely consumed first, limiting the amount of product formed. Additionally, the percentage yield of 4-tert-butylcyclohexanol, based on theoretical and actual yield comparison, needs to be determined.
