**Multiplication and Division with Significant Figures**
Perform the following calculations. Ensure each answer contains the correct number of significant figures.
1. Calculate:
\[
7.808 \, \text{cm} \times 2.2 \, \text{cm} = \, \_ \_ \, \text{cm}^2
\]
2. Calculate:
\[
\frac{20.947 \, \text{mol}}{1 \, \text{L}} \times 45 \, \text{L} = \, \_ \_ \, \text{mol}
\]
3. Calculate:
\[
\frac{419.9 \, \text{m}}{53.888 \, \text{s}} = \, \_ \_ \, \frac{\text{m}}{\text{s}}
\]
