The correct answer is: $0.75\text{ L}$
Explanation
You convert milliliters to liters knowing that $1\text{ L} = 1000\text{ mL}$. Divide the milliliters by 1000 to get liters.
Steps:
- Relationship: $1\text{ L} = 1000\text{ mL}$
- Convert: $$\frac{750}{1000} = 0.75$$
- Include units: $0.75\text{ L}$
Therefore, 750 mL equals $0.75\text{ L}$.
