Answer:
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 [tex]N_0[/tex].
Avogadro constant:-
[tex]N_a=6.023\times 10^{23}[/tex]
Let the molar mass of the element is x g/mol
So,
[tex]6.023\times 10^{23}[/tex] atoms have a mass of x g
Also,
[tex]3.89\times 10^{24}[/tex] atoms have a mass of [tex]\frac{x}{6.023\times 10^{23}}\times 3.89\times 10^{24}[/tex] g
This mass is equal to 848 g
So,
[tex]\frac{x}{6.023\times 10^{23}}\times 3.89\times 10^{24}=848[/tex]
x= 131.3 g/mol
This mass correspond to xenon.
