Answer : The density of rock reported should be, 3.1 g/mL
Explanation :
Mass of rock = 18.3 g
Original volume of water = 11.1 mL
New volume of water = 17.0 mL
First we have to calculate the volume of rock.
Volume of rock = New volume of water - Original volume of water
Volume of rock = 17.0 mL - 11.1 mL
Volume of rock = 5.9 mL
Now we have to determine the density of rock.
Formula used :
Thus, the density of rock reported should be, 3.1 g/mL
