Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table.
We know because of DNA testing in general.
Answer:
The resultant molarity is 0,7 M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We use the formula for dilutions:
C1 x V1 = C2 x V2
3,5 M x 20 ml= C2 x 100ml
C2= (3,5 M x 20 ml)/100ml
<em>C2= 0,7M</em>
