The quantity of element D in grams that are needed to form compound [tex]CD_2[/tex] is equal to 16 grams.
Given the following data:
- Mass of element C = 3 grams
- Mass of element D = 8 grams
- New chemical compound = [tex]CD_2[/tex]
To determine how many grams of element D are needed to form compound [tex]CD_2[/tex]:
First of all, we would write a balanced chemical equation for the chemical reaction as follows:
[tex]C + D_2 --> CD_2[/tex]
By stoichiometry:
Three (3) grams of of element C react with two (2) atoms of eight (8) grams of element D.
Therefore, we would multiply the mass of element D by two (2), in order to determine how many grams of element D are needed to form compound [tex]CD_2[/tex].
[tex]D_2 = 2 \times 8\\\\D_2 = 16 \;grams[/tex]
