Question
Transcribed Image Text:**Topic: Counting Significant Digits When Measurements Are Multiplied or Divided**
**Instructions:**
Multiply or divide the following measurements. Be sure each answer you enter contains the correct number of significant digits.
**Problems:**
1. \( \frac{180.2 \, \text{g}}{37.7 \, \text{mL}} = \, \_\_\_\_\_\_ \, \frac{\text{g}}{\text{mL}} \)
2. \( 0.93 \, \frac{\text{mol}}{\text{L}} \times 4.625 \, \text{L} = \, \_\_\_\_\_\_ \, \text{mol} \)
3. \( 20.94 \, \frac{\text{mol}}{\text{L}} \times 25. \, \text{L} = \, \_\_\_\_\_\_ \, \text{mol} \)
**Tools Provided:**
- A clear input box for each problem to enter your answer.
- A button to indicate powers of ten (\( \times 10 \)) if needed.
- Options to clear or reset your answer.
**Note:** Ensure that your answers respect the rules of significant digits in scientific calculations.
