During a lab activity, students calculate the density of an element to be 7.78 g/cm3. the density listed on the periodic table is 7.13 g/cm3. calculate the percent error and identify the element.

Percent error = 9.12 %

The element is zinc

Explanation:

The percent error can be calculated using the formula:

%error = * 100%

%error = * 100 % = 9.12%

To identify the element we need to look in the periodic table for any element that has such a density. In this case it's zinc, Zn.

what does the table look like

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
