Water (H2<span>O) can be </span>called<span> a molecule or a compound because it is </span>made of hydrogen<span> (H) and </span>oxygen<span> (O) atoms. There are two main types of chemical bonds that hold atoms together: covalent and </span>ionic<span>/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds.
Hope this helps.</span>
Answer:
The concentration of dye is 2.29 mg/mL.
Explanation:
According to Beer's law the absorbance (A) of a solution is proportional to its concentration (c). The best fit curve line to an A vs. c plot has a slope of 0.1815 mL/mg and intercept of 0.0477. The resulting equation is:
A = 0.0477 + 0.1815 mL/mg . c
If a solution has an absorbance of 0.464, the concentration of dye will be:
0.464 = 0.0477 + 0.1815 mL/mg . c
c = 2.29 mg/mL
Answer: 19mL
