1 mole is equal to 6.0220 x 1023 atoms of any element.
Answer:
Electronic configuration of Ga³⁺:
Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s⁰ 3d¹⁰ 4p⁰
Explanation:
Gallium is present in group 13.
It has 3 valance electrons.
Electronic configuration:
Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p¹
There are two possibilities of gallium to form cation.
By removing one 4p electron to form Ga +1 cation.
By removing two 4s electrons and one 4p to form Ga +3 cation.
Gallium is preset in group thirteen that's why common oxidation state is +3.
Electronic configuration of Ga⁺:
Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁰
Electronic configuration of Ga³⁺:
Ga = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s⁰ 3d¹⁰ 4p⁰

Explanation:
1kg x 0,37=370gHCL
370g/36,5g/mol=10,137mol/kg
1l=1,185kg
10,137 x 1,185kg/l =12,0mol/l
(x/ml(12mol HCL)*12mol/L)/100ml=0,025mol/L
x=
