Answer:
There are 7000 milliliters in 7 liters.
Explanation:
To convert liters to millimeters, we need to know the conversion factor between the two units.
The conversion factor between liters and millimeters is 1 liter = 1000 milliliters.
Since there are 1000 milliliters in a liter, we can use this conversion factor to convert 7 liters to millimeters.
To do this, we can multiply the given value in liters by the conversion factor:
7 liters * 1000 milliliters/liter = 7000 milliliters.
Therefore, there are 7000 milliliters in 7 liters.
