We Can Be Sure That a Mole of Table Sugar

Question

We can be sure that a mole of table sugar and a mole of vitamin C are equal in their
A) mass in daltons.
B) mass in grams.
C) volume.
D) number of atoms.
E) number of molecules.

Accepted Answer

A mole of any substance contains the same number of entities, which is Avogadro's number (6.022 x 10^23). Therefore, a mole of table sugar and a mole of vitamin C both contain the same number of molecules, making E the correct choice. The mass of each substance in grams will be different since they have different molar masses, making B incorrect. The volume of a substance depends on its density and is not necessarily the same for different substances, making C incorrect. The number of atoms in a substance will depend on its molecular formula and is not necessarily the same for different substances, making D incorrect. The term "mass in daltons" is synonymous with molar mass, making A redundant.
