Question
**Experiment Overview:**

An unknown food dye is analyzed by the method used in this experiment. The absorbance of five standard solutions is plotted against their concentration (molarity), resulting in a straight line. The relationship is described by the formula:

\[ \text{Abs} = 2.250x \]

**Experiment Procedure:**

- An unknown food dye solution is diluted.
- The absorbance of this diluted solution is measured and found to be 0.65.

**Objective:**

Determine the molarity of the diluted unknown solution to two significant figures.

---

**Instructions for Calculation:**

1. Use the given absorbance value (0.65) and the formula (Abs = 2.250x) to calculate the molarity.

\[ 0.65 = 2.250x \]

2. Solve for \( x \) to find the molarity of the diluted solution.
