The density of water is 1.0 g/mL. How many deciliters of water will fill a 0.5-L bottle?

The question has nothing to do with density. Convert .5L to deciliters.

5000 deciliters.

5000 deciliter

To determine how many deciliters of water will fill a 0.5-L bottle, we first need to convert liters to deciliters.

1 liter (L) is equal to 10 deciliters (dL). So, we can convert 0.5 L to deciliters as follows:

0.5 L x 10 dL/L = 5 dL

Therefore, a 0.5-L bottle can be filled with 5 deciliters of water.
