Explanation:
The formula of acetic acid is CH3COOH => C2H4O2.
So, the acetic acid has the same number of atoms of carbon (C) than of oxygen (O).
Therefore, the sample that contains 96.5 moles of carbon, will contain also 96.5 moles of O.
Answer: 96.5 moles of oxygen.
Moles pf mgcl2= 2,11/M mgcl2=2,11/95= 0,0222
Molarity=0,0222/1,5=0,0148 M.
I hope this is correct.
Explanation: Outer shell electronic configuration for Group 18 is :
( have 8 electrons in the outer shell)
The electronic configurations for other groups are:
( have 1 electron in the outer shell}
( have 2 electrons in the outer shell)
( have 5 electrons in the outer shell)
( have 6 electrons in the outer shell)
( have 7 electrons in the outer shell)
Comparing the electron configurations of group 18 to other groups.
Group 18 has fully filled outer shell, that is 8 electrons in the outer shell, while others are partially filled.
