Answer:
helium
Explanation:
it has 8 valence electrons which fills its outer energy level making it have a stable arrangement of electrons hence least reactive
The volume of the given solution is 2.5 L.
<u>Explanation:</u>
Volume of the solution = 2500 mL
We have to convert it into litres as,
1000 mL = 1 litre
To convert ml into litres we have to divide the millilitres by 1000, so that it can be converted into L.
Here given volume is 2500 mL.
Volume in L =
= 2.5 L
So the volume of the solution is 2.5 L.
