Perform the following conversions. Report your answer to the correct number of significant figures. Use the "E" format to enter a number in scientific notation (ex: 6.022 × 1023 = 6.022E23)
a. 540 mL = Blank 1 L
I
b. 0.00233 km = Blank 2 m
c. 0.0000145 g = Blank 3 ug
d. 0.0192 L = Blank 4 mL

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: \( \text{Blank 4} = 19.2 \, \text{mL} \)
