Problem 1:
WARRIOR [948]

Answer:

12,302.59 mL

Explanation:

The problem above requires the conversion of the unit of volume, <em>gallon</em>, to <em>milliliter. </em>

You have to take note of the following values before computing.

  • 1 L is equivalent to 0.264172 gallons
  • 1 L is equivalent to 1,000 ml

Now, we can do the conversion. Let's convert<u><em> 3.25 gallons to milliliter</em></u>.

1. 3.25 gallons x \frac{1 L}{0.264172 gallons} = 12.30259 L

2. 12.30259 L x \frac{1,000 ml}{1 L} = 12,302.59 mL

Therefore, <u><em>3.25 gallons of distilled water is equivalent to 12,500 mL of distilled water.</em></u>
