What number of mols of kcl are in 5.6 ml a solution of0.12
molar kcl? (give answer with units to the appropriate numberof sf.)
do not use exponential notation.

Moles of potassium chloride = 0.000672 moles

Explanation:

Considering:

Or,

Given :

For potassium chloride :

Molarity = 0.12 M

Volume = 5.6 mL

The conversion of mL to L is shown below:

1 mL = 10⁻³ L

Thus, volume = 5.6×10⁻³ L

Thus, moles of potassium chloride  :

Moles of potassium chloride = 0.000672 moles

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
