Answer:

The answer to your question is:       C₁₈ H₂₇ N O₃

Explanation:

Data

Carbon = 70.79 g

Hydrogen = 8.91 g

Nitrogen = 4.58 g

Oxygen = 15.72 g

Process

AT C = 12 g

AT H = 1 g

AT N = 14 g

AT O = 16 g

                   Carbon

                                  12 g ------------------------  1 mol

                           70.79  g -------------------------   x

                                 x = (70.79 x 1) / 12

                                 x = 5.9 mol of C

                  Hydrogen

                                   1 g -----------------------  1 mol

                                8.91 g ---------------------   x

                                  x = (8.91 x 1) / 1

                                  x = 8.91 mol of H

                  Nitrogen

                                 14 g ---------------------- 1 mol

                                4.58 g -------------------   x

                                   x = (4.58 x 1) / 14

                                   x = 0.33 mol

                  Oxygen

                               16 g ------------------------  1 mol

                               15.72 g --------------------   x

                                  x = (15.72 x 1)/16

                                 x = 0.98

Divide by the lowest number of moles

Carbon               5.9 / 0.33     =  17.9   ≈ 18

Hydrogen           8.91 /  0.33  =   27

Nitrogen             0.33 / 0.33  =    1

Oxygen               0.98 / 0.33 =    2.9  ≈ 3

                             C₁₈ H₂₇ N O₃

Answer:

A diamond is a pure substance because it is made of one element.

Explanation:

From the crystalline structure model of the diamond, we can see that we only have just one element represented by the green balls connected in a cross linked fashion to one another. Therefore, one can rightly conclude that this is a pure substance made up of one element.

In a pure substance, all parts are homogeneous and composition is definite.
