Question

How much sodium dihydrogen phosphate is required

Answer 1

To determine the amount of sodium dihydrogen phosphate (NaH₂PO₄) required for a specific application, you would need to know the intended use, such as preparing a buffer solution, adjusting pH, or for a specific concentration in a reaction.

Here’s how you could calculate it if you have a specific scenario:

1. **Determine the Desired Concentration**: Decide how concentrated you want your solution to be (e.g., molarity, weight/volume percent).

2. **Calculate the Amount Needed**:
- If you want to make \(X\) liters of a solution at a concentration of \(Y\) molarity, use the formula:
\[
\text{grams of NaH₂PO₄ needed} = Y \text{ (mol/L)} \times X \text{ (L)} \times \text{molar mass of NaH₂PO₄ (g/mol)}
\]
- The molar mass of sodium dihydrogen phosphate is approximately 119.98 g/mol.

3. **Convert to Practical Units if Necessary**: Convert grams to a more practical unit (e.g., milligrams) if you're working with small quantities.

If you provide specific details regarding concentration and volume, I can assist you in calculating the exact amount of sodium dihydrogen phosphate needed.
