For an investigation a student records data about four unknown substances. data, for, unknown, substances, substance, mass, grams, volume, centimeters, cubed, density, grams, per, centimeter, cubed, 1, 6.95, 4.0, 2, 4.54, 2.0, 3, 5.40, 3.0, 4, 10.35, 5.0,

The student then calculates the densities of the unknown substances and compares them with the table of densities of known substances shown below.

densities, of, some, known, substances, substance, density, grams, per, centimeter, cubed, calcium, 1.54, carbon, 2.27, magnesium, 1.74, phosphorus, 1.82, platinum, 21.46, sulfur, 2.07,

Which unknown substance is most likely carbon?

omparing the values of the strung density, the one that is closest to carbon is number 2

Explanation:

In this exercise we are given the mass and volume of a body, we are asked to calculate the density, using the equation

          ρ = m / V

in the third and fourth column of the table is the density and the substance with the closest value

#    mass   volume  density   material

        (gr)      (cm³)       (gr/cm³)

1      6.95      4.0          1.74       magnesium

2     4.54      2.0          2.27       carbon

3     5.40      3.0          1.80        phosphorus

4    10.35      5.0         2.07        sulfur

When comparing the values of the strung density, the one that is closest to carbon is number 2
