To determine how many liters (L) are in 450 milliliters (mL), we need to use the conversion factor between milliliters and liters. The relationship between milliliters and liters is:
[tex]\[ 1 \text{ L} = 1000 \text{ mL} \][/tex]
This conversion factor means that one liter is equivalent to one thousand milliliters.
To convert milliliters to liters, we can use the following formula:
[tex]\[ \text{Volume in liters} = \frac{\text{Volume in milliliters}}{1000} \][/tex]
Given the volume in milliliters is 450 mL, we can plug this value into the formula:
[tex]\[ \text{Volume in liters} = \frac{450 \text{ mL}}{1000} \][/tex]
Performing the division:
[tex]\[ \text{Volume in liters} = 0.45 \text{ L} \][/tex]
Therefore, 450 mL is equal to 0.45 L.
So the correct answer is:
A. 0.45 L
