Question

An object of mass 50 gram has a volume of 20cm calculate the density of object if the density of water 1g cm cube state wheather the object will float or sink in water

Answer 1

$\huge{\underline{\underline{\sf{\blue{SOLUTION:-}}}}}$

⠀

$\sf{\underline{\pink{Answer-}}}$

⠀

• The density of the object is 2.5 g/cm³

⠀

$\sf{\underline{\pink{Given-}}}$

⠀

• An object of mass 50 gram has a volume of 20cm.

⠀

• The density of water is 1 g/cm³.

⠀

$\sf{\underline{\pink{Calculate-}}}$

⠀

• We have to calculate the density of object.

⠀

$\sf{\underline{\pink{Explanation-}}}$

⠀

$\sf{\underline\green{Formula\:Used\:Here-}}$

⠀⠀

$\bigstar\boxed{\sf{\red{Density= \frac{Mass \: of \: the \: object}{Volume \: of \: the \: object} }}}$

⠀

$\longrightarrow\sf \: Mass \: of \: the \: object=50g$

⠀

$\longrightarrow\sf \: Volume \: of \: the \: object=20 {cm}^{3}$

⠀

$\sf{\underline{\pink{Putting\:the\:values:-}}}$

⠀

$\longrightarrow\sf \: Density \: of \: the \: object= \frac{50 \: g}{20 \: {cm}^{3} }$

⠀

$\longrightarrow \sf \: 2.5g/ {cm}^{2}$

⠀

• Thus, the density of the object is 2.5 g/cm³.

⠀

• Since the density of the object is 2.5 g/cm³ is greater than the density of water 1 g/cm³. Thus, the object will sink in water.

Answer 2

Àñśwèŕ

: )

Mass of an Object = 50 gm,

The Volume of an object = 20 cm

&

The Density of water is 1gm / cm3

So,

We Have to find the Density,

Density = Mass / Volume

Now putting the values

Density = 50 / 20

Density = 2.5gm / Cm^3
