Find the weight of `NaOH` in its 50 milli equivalents.

Explanation

To find the weight of NaOH in 50 milliequivalents, we can follow these steps:

### Step 1: Determine the Molecular Weight of NaOH
The molecular weight of sodium hydroxide (NaOH) can be calculated by adding the atomic weights of its constituent elements:
- Sodium (Na) = 23 g/mol
- Oxygen (O) = 16 g/mol
- Hydrogen (H) = 1 g/mol

So, the molecular weight of NaOH is:
\[ \text{Molecular Weight of NaOH} = 23 + 16 + 1 = 40 \text{ g/mol} \]

### Step 2: Understand the Relationship Between Equivalents and Weight
1 gram equivalent of NaOH corresponds to 1000 milliequivalents and has a weight of 40 grams. Therefore, we can establish the following relationship:
\[ 1 \text{ gram equivalent of NaOH} = 1000 \text{ milliequivalents} = 40 \text{ grams} \]

### Step 3: Calculate the Weight for 1 Milliequivalent
To find the weight of NaOH for 1 milliequivalent, we can set up the equation:
\[ \text{Weight for 1 milliequivalent} = \frac{40 \text{ grams}}{1000 \text{ milliequivalents}} = 0.04 \text{ grams} \]

### Step 4: Calculate the Weight for 50 Milliequivalents
Now, to find the weight of NaOH in 50 milliequivalents, we multiply the weight for 1 milliequivalent by 50:
\[ \text{Weight for 50 milliequivalents} = 50 \times 0.04 \text{ grams} = 2 \text{ grams} \]

### Conclusion
The weight of NaOH in 50 milliequivalents is:
\[ \text{Weight of NaOH} = 2 \text{ grams} \]
