Answer:
0.9
Explanation:
The pka represents the force by which the molecules need to dissociate for the acids ,
Hence , lower the pka stronger will be the acid and that therefore will dissociate completely and vice versa , for a weak acid higher the pka .
And in case of a base , it will be completely reversed , lower pKa , weaker base ,
and higher pKa , stronger base .
From the data of the question ,
0.9 is the lowest value of the pKa , hence , weakest base .
the answer is A. I (iodine)
no worries

Answer:
<h2>D) 6</h2>
Explanation:
since, n = molar mass / empirical formula mass
Empirical formula mass = Total mass of atoms present in empirical formula
CHCl = 12+1+35.5
= 48.5
Given, Molar mass = 290.8 g.
So, n = 290.8/48.5
= 5.995 , that is approx 6.
So, Molecular formula = n × Empirical formula
= 6 × CHCl
= 
So, Number of C = 6
