About 7.6 1/2 liters to equal one US gallon.
To make a liter of water, you would need two 500ml bottles of water. This is because 1 liter is equivalent to 1000ml. Therefore, two 500ml bottles combined would give you a total of 1000ml or 1 liter of water.
The answer depends on the capacity of the bottles of water!
This depends on the size of the bottle of water. The typical bottle of water is about 16 ounces. Because a gallon is 128 ounces, it would amount to about 8 bottles of water.
by using 500ml. of bottles and food coloring.
If you drink 10 and 2/3 of them, it is a certainty that you will very soon make a gallon.
Imperial: 160 imperial oz = 1 imperial gallon160 oz / 16 oz = 1010 - 16 imperial ounces make an imperial gallonUS: 128 US oz = 1 US gallon128 oz /16 = 88 - 16 US ounces make a US gallon
7.574 bottles (rounded)
Figure out how many oz. are in both the bottle of water and a gallon. Then see how many bottles of water you can fit in a gallon. Theres your answer.
32 ounces = 1 quart.You need four of those to make one gallon.
1000ml in a litre, so two 500ml bottles = 1litre
