Question

question 2 (0.5 points) saved reflecting back on last week, why do chemists use moles instead of individual atoms or molecules? moles are more accurate than atoms/molecules. most chemical reactions only use single atoms. atoms are very small, and using their actual counts (like 6.022×10²³) would be inconvenient because there are so many of them in even small sample sizes. counting atoms would require a microscope, but counting moles does not.

Explanation:

Atoms and molecules are extremely small. Even in tiny samples, their numbers are astronomically large (e.g., Avogadro's number $6.022\times 10^{23}$). Using moles (a unit representing a specific number of entities) simplifies calculations and measurements in chemistry compared to dealing with individual atom/molecule counts.

Answer:

Atoms are very small, and using their actual counts (like $6.022\times 10^{23}$) would be inconvenient because there are so many of them in even small sample sizes.
