State the number of significant figures in the following quantities a. 3.00100 g b. 0.0200 s c. 0.0023°C d. 0.0000055 g e. 1.6402 g f. 3.40 x 103 mL g. 1.020 L

Let's evaluate the number of significant figures for each quantity:

a. **3.00100 g**  
   - All non-zero digits and zeros between non-zero digits are significant. Trailing zeros after a decimal point are also significant.  
   - **Significant Figures**: 6

b. **0.0200 s**  
   - Leading zeros are not significant, but trailing zeros after a decimal point are.  
   - **Significant Figures**: 3

c. **0.0023°C**  
   - Leading zeros are not significant.  
   - **Significant Figures**: 2

d. **0.0000055 g**  
   - Leading zeros are not significant.  
   - **Significant Figures**: 2

e. **1.6402 g**  
   - All non-zero digits are significant.  
   - **Significant Figures**: 5

f. **3.40 x 10³ mL**  
   - In scientific notation, the digits in the coefficient (3.40) are significant. The exponent doesn't affect the count of significant figures.  
   - **Significant Figures**: 3

g. **1.020 L**  
   - Trailing zeros after a decimal point are significant.  
   - **Significant Figures**: 4

### Summary of Significant Figures:
- a. 6
- b. 3
- c. 2
- d. 2
- e. 5
- f. 3
- g. 4
