Measure the mass of the metal closures.
Calculate the mass
of 1 mL aluminium
Matter is anything that has a mass and a volume.
What you
need
8 aluminium closures of the Liquemin
bottles from the previous experiment, two-pan scale, 1-gram weight.
Experiment
* Left: Here you can see again
how the volume of the closures was measured in the previous experiment:
8 of them had a volumen of
0.6 mL.
*Right: The girls of
primary 4 found that the weight of 5 aluminium closures was 1.0 grams.
Evaluation
8 aluminium closures have a weight of 8/5 g = 1.6
g and a volume of 0.6 mL. That means:
1 mL aluminium has a weight of 1.6/0.6 g = 2.7
g
