The mass of one mole of helium is 4.00 g. How many atoms of helium are present in the sample? Let us imagine that there is a new discovery about the magnitude of the Avogadro's number (N). It was found out that the N, is 25% smaller than the previous value. How will this new discovery affect the calculated number of atoms of helium? Will the new value of NA cut the mass of one mole of helium? Explain your answer.

Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.
