Question

Compare: While the number of atoms in a mole is constant, the number of grams in a mole changes based on the element. The number of grams in a mole (g/mol) is known as its molar mass, and has the same numerical value as an element's atomic mass (in u). Use the Gizmo to find the atomic and molar mass of the following elements. Use proper units.

S Atomic mass:

Al Atomic mass:

S Molar mass:

Al Molar mass:​

Answer 1

S Atomic mass: 32.06 AMU

Al Atomic mass: 26.98 AMU

S Molar mass: 32.06 g/mole

Al Molar mass:​ 26.98 g/mole

Step-by-step explanation:

The Periodic Table has the unique property that the atomic masses are numerically the same as the molar masses. Thus, g/mole may be subastituted for AMU: they are equivalent. Just change AMU to g/mole.
