Answer:
There are many infectious diseases for which we don't have an effective treatment. In these cases, the scientific community is working to understand the molecular mechanisms used by these pathogens to attack human cells. From a medical perspective, it is imperative to use treatments to improve the patient's life quality.
Answer:
c. 1.4 x 10²³ oxygen atoms
Explanation:
The number of oxygen atoms in one molecule of CH₃COOH is 2.
Avogadro's constant relates the number of molecules in one mole:
6.022 × 10²³ mol⁻¹
Thus, the number of oxygen atoms in one molecule of acetic acid can be converted to the number of oxygen atoms in one mole of acetic acid:
(2 oxygen atoms / molecule)(6.022 × 10²³ molecule / mol) = 1.204 x 10²⁴ atoms per mole
Finally, the number of oxygen atoms in 0.12 moles of acetic acid are calculated:
(1.204 x 10²⁴ atoms / mol)(0.12 mol) = 1.4 x 10²³ atoms/mol
