Question

please answer question no. 53

Answer 1

mass of bottle filled with water(m1) = 150g

mass of empty bottle (m2) = 50g

mass of water(m) = m2 - m1 = 150-50 = 100g
__________________

density of water = 1 g/cm^3

volume of water(v) = mass/density = 100/ 1 = 100cm^3

internal volume of bottle (v1)= volume of water = 100 cm^3
___________________

External volume of bottle(v2) = 125 cm^3

Thus, volume of the bottle material (v) = v2 - v1 = 125 - 100 = 25 cm^3
____________________

Now, mass of bottle = 50g

volume of bottle = 25 cm^3

density = mass/volume = 50/25 = 2 g/cm^3

Hence, density of material of bottle is 2 g/cm^3

Answer 2

$\huge\mathcal{\fcolorbox{cyan}{black}{\pink{ĄNsWeR࿐}}}$

mass of bottle filled with water(m1) = 150g

mass of empty bottle (m2) = 50g

mass of water(m) = m2 - m1 = 150-50 = 100g

__________________

density of water = 1 g/cm³

volume of water(v) = mass/density = 100/ 1 = 100cm³

internal volume of bottle (v1)= volume of water = 100 cm³

___________________

External volume of bottle(v2) = 125 cm³

Thus, volume of the bottle material (v) = v2 - v1 = 125 - 100 = 25 cm³

____________________

Now, mass of bottle = 50g

volume of bottle = 25 cm³

density = mass/volume = 50/25 = 2 g/cm³

Hence, density of material of bottle is 2 g/cm³.
