Question

While determining the density of the material of a sphere using a spring balance and measuring cylind a student noted the following readings: (a) Reading of water level in the cylinder without sphere in it = 56 ml (b) Reading of water level in the cylinder with sphere in it = 64 ml If the mass of sphere is 80 g, calculate the density of the sphere.​

Answer 1

Answer:

youranswer

Explanation:

Mass = 81 grams = 0.008 kg

Initial reading = 54 ml

Final reading = 63 ml

Volume of sphere = Amount of water displaced by it

Amount of water displaced =

Final reading - Initial reading

= 63 - 54

= 9ml

Volume = 9 ml = 9 cm³

[1 ml = 1 cm³]

Density = Mass / Volume

= 81/9

= 9 g/cm³

= 9000 kg/m³

[1g/cm³ = 1000 kg/m³]
