Answer:
1.056 g/mL
Explanation:
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.
Given data:
density= ?
volume of water = 50 mL
volume of water + rock = 67 mL
mass= 18 g
first of all we will calculate the volume of rock.
volume of rock = volume of (water + rock) - volume of water
volume of rock = 67 mL - 50 mL
volume of rock = 17 mL
Now we will put the values in the formula,
d= m/v
d= 18 g/ 17 mL
d= 1.056 g/mL
The density of rock is 1.056 g/mL
