Density

Aim: To investigate the relationship between the position of an element in the periodic table and its density

Materials:
- Digital balance (400g/0.01g)
- Plastic ruler(300mm/1mm)
- Triple beam balance (610g/1g)
- Displacement vessel
- Measuring cylinder (50ml/1ml)
- Samples of the following elements (Mg, C, Al, S, Fe, Ni, Cu, Zn, Sn, Pb)
Diagram: onseparate page
Method
1. Measure the mass and volume of the samples with the methods shown above. For each sample, use the indicated method.
- Measure Mg with method 1 for volume and method 2 formass.
- Measure C with method 1 for volume and method 2 for mass.
- Measure Al with method 3 for volume and method 2 for mass.
- Measure S with method 1 for volume and method 1 formass.
- Measure Fe with method 3 for volume and method 1 for mass.
- Measure Ni with method 1 for volume and method 1 for mass.
- Measure Cu with method 1 for volume and method 2 for mass.- Measure Zn with method 2 for volume and method 2 for mass.
- Measure Sn with method 2 for volume and method 1 for mass.
- Measure Pb with method 3 for volume and method 1 for mass.2. Calculate the density for each element using the formula:
