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

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

$=15+28.8=43.8g$
