Final answer:
The volume that is equal to 1/1000000000 the volume of 1 liter can be expressed in nanoliters.
Step-by-step explanation:
The volume that is equal to 1/1000000000 the volume of 1 liter can be expressed in nanoliters.
When converting from a larger unit to a smaller unit, we multiply by 1000. Since 1 liter is equal to 1000 milliliters (mL) and 1 milliliter is equal to 1000 microliters (μL), we can continue this conversion down to nanoliters.
Therefore, the volume that is equal to 1/1000000000 the volume of 1 liter is 1 nanoliter (nL).
