Avogadro's number (6.0221415 × 10^23) determines the number of atoms in a mole. Thus, 1.5 moles of any elements will contain 1.5 x (6.0221415 × 10^23) atoms. The molar mass will vary, but the number of atoms will be the same.

Isn't chem fun?

Ummm...Mossback just gave you the answer.

"1.5 moles of any elements will contain 1.5 x (6.0221415 × 10^23) atoms"

Multiply 1.5 x 6.0221415, then it's that number times 10 to the 23rd power.
