The mass of the of the ball is 125g.
What should be its volume density . 0500 g/cm cube ? Also find the density in si unit
and its relative density
Answers
Answer:
I will tell you the formulas...
To work out density: p = m / V.
To work out the mass: m = p x V.
To work out the volume: V = m / p.
Answer:
Volume of the ball is 0.25 cm³.
Density in SI units is 5 x 10⁵ kg m⁻³.
Relative density of the ball is 500 g cm⁻³.
Given:
Mass of the ball, m = 125 g
Density, d = 500 g/cm³
Find:
The volume of the ball.
Density in SI units.
Relative Density.
Solution:
Let the volume of the ball be V.
As we know,
Density = Mass / Volume
d = m / V
V = m / d
V = 125 / 500
= 0.25 cm³
Hence, volume of the ball is 0.25 cm³.
Density in SI units = Density in CGS units x 1000
= 500 x 1000
= 500000 kg m⁻³
= 5 x 10⁵ kg m⁻³
Hence, density in SI units is 5 x 10⁵ kg m⁻³.
Relative Density = Density of ball/Density of water at 4°C
= 500/1
= 500 g cm⁻³
Hence, the relative density of the ball is 500 g cm⁻³.
