Question

the mass of 1 mole of an element (in grams) is the same as which quantity?
a. the atomic number of the element times avogadros number
b. the atomic number of the element
c. the atomic mass of the element in atomic mass units
d. the atomic mass of the element times avogadros number

Explanation:

One mole of an element has a mass (in grams) equal to its atomic mass in atomic mass units. The atomic number represents the number of protons and is not related to the mass of one - mole. Multiplying by Avogadro's number is not relevant here as the molar mass (mass of 1 mole) is numerically equal to the atomic mass in amu.

Answer:

C. The atomic mass of the element in atomic mass units
