(b) Given that, mass of an object = 14.01 g
Volume of water alone in beaker = 25.2 mL
Volume of water and object in beaker = 33.6 mL
Volume of object = Volume of water and object in beaker - Volume of water alone in beaker = 33.6 - 25.2 = 8.4 mL
Now, Density = mass / Volume = 14.01 g / 8.4 mL = 1.67 g/mL
