Question
**Chemical Reaction and Equivalent Mass Calculations**

---

For the following reaction:

\[ 2 \ \text{HClO}_4 + \text{Ca(OH)}_2 \longrightarrow \text{Ca(ClO}_4)_2 + 2 \ \text{H}_2\text{O} \]

1. **What is the equivalent mass of \(\text{Ca(OH)}_2\)?**  
   \[ \text{\_\_\_\_ g/equiv} \]

2. **Calculate the number of equivalents in 38.6 grams of \(\text{Ca(OH)}_2\).**  
   \[ \text{\_\_\_\_ equiv} \]

_Image Explanation:_

- There are two questions presented regarding a chemical reaction involving calcium hydroxide, \(\text{Ca(OH)}_2\).
- The first question asks for the equivalent mass of \(\text{Ca(OH)}_2\), to be provided in grams per equivalent (g/equiv).
- The second question requires calculating the number of equivalents in 38.6 grams of \(\text{Ca(OH)}_2\), with the value to be provided in equivalents (equiv).

This exercise helps understand the concept of equivalent mass and its application in stoichiometric calculations in chemical reactions.
