Answer:
Explanation:
<h3>Electronic configuration:</h3>The outermost/valence shell is the second one, seeing from the electronic configuration.
<h3>Valence electrons:</h3>= 2 + 1 = 3 (electrons are raised to the power in the electronic configuration)
Since, the valence shell here is 2, the electrons of second shell will be counted as valence electrons.

Question:
2. Ag.SO.
a) Molar Mass:
b) Percent Composition of Ag:
c) Percent Composition of S:
d) Percent Composition of O:
Answer:
a) Molar Mass: 155.93 Kg
b) Percent Composition of Ag: 69%
c) Percent Composition of S: 20.5%
d) Percent Composition of O: 10.2%
Explanation:
Molar mass = molar mass of Ag + molar mass of S + molar mass of O
=>107.87+32.06+16
=> 155.93 Kg
Percent Composition of Ag
=
=
= 0.69 \times 100
= 69%
Percent Composition of S:
=
=
= 0.205 \times 100
= 20.5%
Percent Composition of O:
=
=
= 0.102 \times 100
= 10.2%
