Step 1:Let's solve this step by step:
Step 2:: Understand the given volume
- We start with 225 mL (milliliters) - We need to convert this to different units to compare with the given options
Step 3:: Convert mL to μL (microliters)
- This can be written in scientific notation as $$2.25 \times 10^{5} \text{ μL}
- 1 mL = 1,000 μL
Step 4:: Convert mL to L (liters)
- 1 mL = $$\frac{1}{1,000}$$ L
- 225 \text{ mL} \times \frac{1}{1,000} = 0.225 \text{ L}
Step 5:: Examine the given options
- Option E: $$0.225 \text{ μL}$$ (too small)
- Option B: 2.25 \times 10^{2} \text{ μL} (too small)
Final Answer
A. 2.25 \times 10^{5} \text{ μL} is equivalent to 225 mL.
