Question #27cd0

Feb 24, 2016

A sample of an element was obtained by a student. After making the appropriate measurements and calculations, the density at ${20}^{\circ} \text{C}$ was determined to be $\text{2.70 g/cm"^3}$.
The student was given a list of the elements at ${20}^{\circ} \text{C}$ which can be viewed at http://www.chemicool.com/densities.html.
The list included a density of $\text{2.702 g/cm"^3}$ for the element aluminum. Therefore, the unknown element was determined to be aluminum.
