In an experiment to determine the density of the given solid (denser than water) by using a spring balance and a measuring cylinder, following obs. we're made:
? Mass of solid is 125g.
? Initial water level in cylinder is 45ml.
? Final water level in cylinder is 69ml.
On the basis of these obs. what is the density of the object if the spring balance showed a reading of 5g before suspending the solid?

Dear Student

$M a s s o f s o l i d = \frac{(F i n a l r e a d i n g o f s p r i n g b a l a n c e - i n i t i a l r e a d i n g o f s p r i n g b a l a n c e) \times g}{g} M a s s o f s o l i d = 125 - 5 = 120 g V o l u m e o f s o l i d = 69 - 45 = 24 m l D e n s i t y = \frac{M a s s}{V o l u m e} = \frac{120 g}{24 c m^{3}} = 5 g / c m^{3}$
