Everyday Science / Chemistry — Multiple-choice practice
- A. It has the same mass as 1 mole of carbon atoms.
- B. It contains the same number of atoms as 1/2 mole of C¹².
- C. It is liberated by 1 mole electrons.
- D. It contains the same number of atoms as 1 mole of hydrogen atoms.
Correct answer
It contains the same number of atoms as 1 mole of hydrogen atoms.
Explanation
Explanation By definition, 1 mole of any element contains Avogadro’s number (6.022 × 10²³) of atoms. So, 1 mole of a metal has the same number of atoms as 1 mole of hydrogen atoms.
