The total mass is the sum of mass of KCl and mass of
water:
total mass = 38 g + 225 g
total mass = 263 g
Therefore the mass percent of KCl is:
% KCl = (38 g / 263 g) * 100%
<span>% KCl = 14.45%</span>

Answer:
False
Explanation:
There are two types of covalent bonding: polar covalent boding and nonpolar covalent bonding. During polar covalent bonding, the electrons are not shared evenly. This is due to the electronegativity differences between the two atoms. During nonpolar covalent bonding, the electrons are shared evenly.
