Let's solve the problem using dimensional analysis step by step.

Step 1: Identify the given quantity and the conversion factor.

• Given: $700 \, \text{nL}$ (nanoliters)
• Conversion factor: $1 \, \text{mL} = 10^6 \, \text{nL}$

Step 2: Set up the dimensional analysis equation.

We want to convert nanoliters (nL) to milliliters (mL). We use the conversion factor so that nanoliters cancel out, leaving milliliters as the unit.

$700 \, \text{nL} \times \left(\frac{1 \, \text{mL}}{10^6 \, \text{nL}}\right)$

Step 3: Perform the calculation.

Now, multiply the quantity by the conversion factor:

$700 \, \text{nL} \times \frac{1 \, \text{mL}}{1,000,000 \, \text{nL}} = \frac{700}{1,000,000} \, \text{mL}$

$= 0.0007 \, \text{mL}$

Final Answer:

The drop contains 0.0007 mL.
