If 3.89 × 1024 atoms of a noble gas is collected and it has a mass of of 848 grams, this element is most likely a. he b. ne c. ar d. kr

Xenon

Explanation:

Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by .

Avogadro constant:-

Let the molar mass of the element is x g/mol

So,

atoms have a mass of x g

Also,

atoms have a mass of g

This mass is equal to 848 g

So,

x= 131.3 g/mol

This mass correspond to xenon.
