Cl: 2 x 35.453
---------------------
110.98 grams
The molar mass of calcium chloride is 110.98 grams.
Hope this helps!
Answer:
equal to [OH-]
Hydrogen ion concentration is more conveniently expressed as pH, which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter. Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−)
Answer:
