The answer is C because it is believed that those two were once connected
The elements in group 7, which fluorine is in also, would have similar properties due to the valence electrons and the configuration. <span />
Answer:
0.2
Explanation:
Given parameters:
Mass of helium = 0.628g
Mass of neon = 11.491g
Mass of argon = 7.613g
Unknown:
Mole fraction of neon = ?
Solution:
The mole fraction of an element is the number of moles of that element to the total number of moles in the gas mixture.
We need to calculate the number of moles of each element first;
Number of moles = 
Molar mass of Helium = 4g/mol
Molar mass of Neon = 20g/mol
Molar mass of Argon = 40g/mol
Number of moles of He =
= 0.16moles
Number of moles of Ne =
= 0.58moles
Number of moles of Ar =
= 0.19moles
Total number of moles = 0.16moles + 0.58moles + 0.19moles = 0.93moles
Mole fraction Neon =
= 0.2
Answer:
The answer is "11.07 g".
