Explanation:
2.04 % hydrogen
32.65% sulphur
65.31% is oxygen
atomic ratio
hydrogen =2.04÷1=2.04
sulphur =32.65÷32=1.02
oxygen =65.31÷16=4.08
simplest ratio
hydrogen = 2.04÷1.02=2
sulphur =1.02÷1.02=1
oxygen =4.08÷1.02=4
empirical formula is H2SO4
In this question given concerning the atom's electron, the number of energy sublevels present in the principal energy level n = 4 is to be determined. For this matter, it should be remembered that the number of sublevels of a certain principal energy level is equal to n. For this item, the number of sublevels is also 4. That is s, p, d and f.
<span>The answer is 335 dm³.</span>

Answer: Option (A) is the correct answer.
Explanation:
Non-electrolytes are the substances which do not dissociate into a solution or water to form ions.
Since, non-electrolytes do not dissociate into ions. Hence, they do conduct electricity.
Thus, we can conclude that it does not dissociate or ionize in water is a characteristic of a non-electrolyte.
Non-electrolytes are neither partially ionizable nor do they conduct electricity poorly. Therefore, out of the given options, only option (A) is the correct answer.
