The answer is Electronegativity
Density = mass / volume
19.3 = 13 / m
m = 13 / 19.3
m = 0.67g

Explanation:
Just Simple Physics :P
Answer: The equations of the above reactions are shown below
Explanation:
(a)
2K(s) + Cl2(g) ==> 2 KCl(s)
(b)
SrO(s) + H2O(aq) ==> Sr(OH)2(aq)
(c)
4Li(s) + O2(g) ==> 2Li2O(s)
(d)
2Na(s) + S (l) ===> Na2S
