why is it possible to do compositional stoichiometry problems in your head?
the number of atoms in a molecule are simple integers
all are correct
the mass of atoms can usually be rounded to simple integer numbers
the value for avogadros number is rounded off to 6 × 10²³

Explanation:

Compositional stoichiometry relies on the simple whole-number ratios of atoms in a molecule (from empirical/molecular formulas), the ability to round atomic masses to simple integers for quick mental calculation, and using a rounded Avogadro's number ($6 \times 10^{23}$) for simplified mental math. All these factors together make mental calculation of these problems feasible.

Answer:

All are correct
