Why doesn't it matter which nonradioactive isotope of oxygen you breathe?
Greeley [361]

Isotopes of an element have same atomic number (number of protons) but vary in the mass number (number of neutrons). The chemical reactivity of an element is not affected by the change in mass number. So, for stable isotopes of Oxygen, (Oxygen-16, Oxygen-17 and Oxygen-18) the biochemical pathway of oxygen breathed in during respiration remains unaffected even with different isotopes. Only the radioactive isotopes of oxygen when breathed in may cause serious health hazards as they emit radiations that may damage the internal organs in the body.

Calculate the number of molecules in 6.7 moles of AlCl3
Greeley [361]

According to the Avogadro’s law I mole of any substance contains = 6.023 x 1023

Number of molecules in one mole= 6.023 x 1023

Therefore number of molecules in 6.7 moles of AlCl3:

6.023x1023 molecules /1.0 mole * 6.7 mole

= 40.3541 x 1023 molecules

= 4.03541 x 1024 molecules
