Answer:
Density = mass/volume (g/cm³)
First find the volume of the stone by subtracting the readings of the measuring cylinder.
Each unit is 4 ml. Take the reading where the lowest point of the curve of the liquid sits.
The first measuring cylinder reading is 24 ml.
The second measuring cylinder reading is 60 ml.
Volume of stone = 60 - 24 = 36 ml
Make sure the units are appropriate. Convert when necessary. ml and cm³ are the same so there is no need to convert. (36 ml = 36 cm³)
Density = 40/36 = 1.11 g/cm³
