Explanation:
An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements.
In general, the size of an atom will decrease as you move from left to the right of a certain period.
Mass of solute = 35 grams
Mass of solution = mass of nacl + mass of water = 35.8 + 184 = 219.8 grams
Concentration = mass of Nacl x 100/mass of solution.
= 35x100/219.8 = 15.92%.
