To answer the question of how many 16 oz water bottles are needed to fill 2 liters, we first need to convert the measurement of 2 liters into fluid ounces. 1 liter is equal to approximately 33.8 fluid ounces. Therefore, 2 liters would be equal to approximately 67.6 fluid ounces.
Next, we divide the total number of fluid ounces (67.6) by the size of each water bottle (16 oz) to determine how many bottles are needed.
67.6 fluid ounces ÷ 16 fluid ounces = 4.225
So, technically, it would require approximately 4.225 16 oz water bottles to fill 2 liters. However, since we cannot have a fraction of a bottle, we would round this number to the nearest whole number.
Rounding 4.225 to the nearest whole number gives us 4.
Therefore, it would take 4 16 oz water bottles to fill 2 liters.
It is important to note that the conversion from fluid ounces to liters is not an exact measurement. The conversion factor is 1 liter = 33.8 fluid ounces, but this may vary slightly depending on the specific conversion factor used.
