Mass of the substance in question = 360 g
Volume of the substance in question = 7.5 cm^3
We already know that
Density of the substance = Mass of the substance / Volume of the substance
= 360/7.5 g/cm^3
= 48 g/cm^3
So the correct option among all the options that are given in the question is the fourth option or option "d". I hope the answer comes to your help.
