Question 8 • Chemistry

Jaime calculates the density of a slab of aluminum (Al) metal. What information does Jaime need to evaluate the accuracy of his calculation?

Answer
A
a line graph that shows how the density of aluminum varies with temperature
B
the accepted value for the density of aluminum
C
a bar graph that shows the densities of different slabs of aluminum
D
the dimensions of the slab of aluminum that he used

Explanation

To evaluate the accuracy of a calculated density, Jaime must compare his result with the accepted value for aluminum’s density. The closer his result is to that accepted value, the more accurate it is. The slab’s dimensions help calculate its density, but they do not provide a standard for judging accuracy.
