Answer:
Electrons arrangement change is almost constant down the group, hence nuclear charge is almost constant.
But the energy levels on which electrons are arranged increase down the group, hence shielding or screening effect increases.
M = amount of the solute / mass of the <span>solvent
0.523 = x / 2.00
x = 0.523 * 2.00
x = 1,046 moles
molar mass KI = </span><span>166.0028 g/mol
</span><span>
Mass = 1,046 * 166.0028
Mass </span>≈<span> 173.63 g
