Question

When a piece of rock of the mass 65 g is dipped
in water, the level of water raises from 175 cm3
to 195 cm3. What is the density of the rock?​

Answer 1

Answer:

density of rock = 3.25gcm3

Explanation:

so first of all we need to know the formula of density

(rho) p = mass/volume

p is symbol for density

so first we will find volume and we have used water displacement method

we know the volume of the water = 175 cm3

when we have dipped the rock the volume is = 195 cm3

so we will subtract 195cm3 - 175cm3 = 20cm3

so the volume of the rock is = 20cm3

and we know the mass 65g

so 65g/20cm3 = 3.25 g cm3

Thank you
