Answer:
The rock is heavier than water and when put into water it will sink.
Explanation:
Given data:
Mass of rock = 2.7 g
Volume = 1.1 cm³
Type of rock = ?
Solution:
From given data we can calculate the density of rock.
If the density of rock is higher than the density of water it means the rock is heavier than water.
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
d = m/v
d = 2.7 g/ 1.1 cm³
d = 2.5 g/cm³
density of water is 1 g/cm³. The rock is heavier than water and when put into water it will sink.
