Let's perform the conversions for each part:

a. 540 mL to Liters

There are 1000 mL in 1 L. $540 \, \text{mL} = \frac{540}{1000} \, \text{L} = 0.540 \, \text{L}$ Answer: $\text{Blank 1} = 0.540 \, \text{L}$

b. 0.00233 km to meters

There are 1000 meters in 1 kilometer. $0.00233 \, \text{km} = 0.00233 \times 1000 \, \text{m} = 2.33 \, \text{m}$ Answer: $\text{Blank 2} = 2.33 \, \text{m}$

c. 0.0000145 g to micrograms (ug)

There are $1 \, \text{g} = 1.0E6 \, \mu\text{g}$. $0.0000145 \, \text{g} = 0.0000145 \times 1.0E6 \, \mu\text{g} = 14.5 \, \mu\text{g}$ Answer: $\text{Blank 3} = 14.5 \, \mu\text{g}$

d. 0.0192 L to milliliters

There are 1000 mL in 1 L. $0.0192 \, \text{L} = 0.0192 \times 1000 \, \text{mL} = 19.2 \, \text{mL}$ Answer: $\text{Blank 4} = 19.2 \, \text{mL}$
