Sagot :
Given :-
- Mass of object = 32.5 g
To Find :-
- Dentity of the material
Solution:-
When the object is placed in a graduated cylinder containing 175 ml of water, the water in the cylinder rises to a level of 187.5 ml , this implies that volume of content in the container has increased , the increased volume is volume of the object placed
So, Volume of object
= Increased Volume - Initial volume
= > 187.5 -175
= > 12.5 ml
Since 1 ml = 1 cm³ we can write
[tex]\quad[/tex]12.5 ml = 12.5 cm³
Now,
[tex]\green{ \underline { \boxed{ \sf{Density= \frac{Mass}{Volume}}}}}[/tex]
Putting Values -
[tex]\begin{gathered}\\\implies\quad \sf Density = \frac{32.5}{12.5} \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf Density = \frac{325}{125} \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf Density = 2.6 g/cm^3 \\\end{gathered} [/tex]
>> The density of the material is 2.6 g/cm³
