Explanation:
Volume of solution in liters:
5.00 x 10² mL / 1000 => 0.5 L
number of moles:
mass of solute / molar mass
21.1 / 119.0 => 0.1773 moles
Molarity = number of moles / volume
M = 0.1773 / 0.5
M = 0.355 mol/L

O.N. of Na = +1
O.N. of O = -2
Let, O.N. of Tin = x
1*2 + x + -2*2 = 0
2+x-4 = 0
x-2 = 0
x = 2
SO OPTION C IS YOUR ANSWER......
