Question

please answer quickly make sure they have the correct number of sig figs

1. **Calculation of Speed**:
- Formula: \( \frac{184.5 \, \text{m}}{0.31 \, \text{s}} = \Box \, \text{m/s} \)
- This calculation involves dividing distance by time to find the speed in meters per second.

2. **Moles Calculation**:
- Formula: \( \frac{20.9 \, \text{mol}}{\text{L}} \times 27. \, \text{L} = \Box \, \text{mol} \)
- This involves multiplying molarity by volume to find the number of moles.

3. **Area Calculation**:
- Formula: \( 0.93 \, \text{cm} \times 0.30 \, \text{cm} = \Box \, \text{cm}^2 \)
- This involves multiplying two lengths to find the area in square centimeters.
