Use the image to answer the question. An illustration shows a horizontal tape diagram divided into 5 equal rectangular sections. The first section is labeled carbon atoms. The remaining 4 sections are labeled hydrogen atoms. Methane gas contains carbon atoms and hydrogen atoms in the ratio of 1:4 . A sample of methane gas contains 90 atoms. What value should be inserted into each rectangle? (1 point) The number should be inserted into each rectangle.

Answer 1

In order to find the value that should be inserted into each rectangle, we need to divide the total number of atoms in the sample (90) by the number of sections (5).

The first section, labeled carbon atoms, represents 1 part out of 5. Therefore, the value that should be inserted into the rectangle for carbon atoms is:

90 atoms / 5 = 18 atoms

The remaining 4 sections, labeled hydrogen atoms, represent 4 parts out of 5. Therefore, the value that should be inserted into each rectangle for hydrogen atoms is:

(90 atoms / 5) * 4 = 72 atoms

So, the value that should be inserted into each rectangle is 18 for carbon atoms and 72 for hydrogen atoms.
