Question #19e8d

Answer 1

Given that an empty relative density bottle has a mass of 15g.when completely filled with water its mass is 39g..

So the mass of water filling the bottle completely is `(39-15)=24g`

So the inner volume of the bottle or the volume of this water will be `="mass of water"/"density of water"`

`=(24g)/(1g/(mL))=24mL`

when the bottle is completely filled with acid of relative density 1.2, the mass of acid in it is `=24mLxx1.2g/(mL)=28.8g`

So mass of the bottle completely filled with acid will be

`="mass of empty bottle" +" mass of acid filling it"`

`=15+28.8=43.8g`
