How many atoms are present in the following molar quantities of various elements?

1.50 moles Fe

1.50 moles Ni

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?

so what is the answer??

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.

YES if you followed the math provided above then it is the correct answer.
