Determining the Density of a Given Solid
Observations:
- Mass of solid = 115g
- Initial reading of water level in measuring cylinder = 45ml
- Final reading of water level in measuring cylinder = 69ml
Calculating Volume:
To determine the density of the given solid, we need to calculate its volume first. We can do this by subtracting the initial water level from the final water level in the measuring cylinder.
- Volume of water displaced = Final water level - Initial water level
- Volume of water displaced = 69ml - 45ml
- Volume of water displaced = 24ml
Density Formula:
Density is defined as the amount of mass per unit volume of a substance. Using the observations and calculations, we can determine the density of the given solid using the formula:
- Density = Mass of solid / Volume of solid
Calculating Density:
- Mass of solid = 115g
- Volume of solid = 24ml (since this is the volume of water displaced by the solid)
- We need to convert the volume of solid to cubic centimeters (cc) since the unit of density is usually expressed in g/cc
- 1 ml = 1 cc
- Volume of solid = 24 cc
- Density = 115g / 24cc
- Density = 4.79 g/cc
Conclusion:
The density of the given solid is 4.79 g/cc.
