Answer 2

Answer: Volume of bottle = 30.25 cm^3

Explanation:

Mass of empty bottle = 20.50g

Mass of bottle with water filled = 50.75g

Mass of bottle with alcohol filled = 45.25g

We have

Density = Mass/Volume

Mass of water in bottle = Mass of bottle with water filled - Mass of empty bottle

Mass of water in bottle = 50.75 - 20.50

Mass of water in bottle = 30.25g

We have

Density of water = 1 g/cm^3

And fluid occupies the whole volume of bottle

Hence

Volume of water = Volume of bottle

Now

Volume of water =  Mass of water in bottle/Density of water

Volume of water =  30.25/1

Volume of water = 30.25 cm^3

Volume of bottle = 30.25 cm^3
