the apple."

Jaime measures the density of a slab of aluminum (Al) metal. What information does Jaime need to evaluate the accuracy of his measurement? the accepted value for the density of aluminum the dimensions of the slab of aluminum that he used a bar graph that shows the densities of different slabs of aluminum a line graph that shows how the density of aluminum varies with temperature

Answers

Answer;

the accepted value for the density of aluminum

Explanation;

  • Density of a substances is given by dividing the mass of the substance by its volume.
  • The density of a substance is constant at constant temperature and pressure. Density is an intensive property of a substance therefore it doesn't depend on the amount of substance present.
  • Therefore, to evaluate the accuracy Jaime needs to get the information about the accepted value for the density of aluminium, to see the closeness of his value and the standard value.
