Word: calcium (s) + hydrochloric acid (aq) → calcium chloride (aq) + hydrogen (g)
Symbol: Ca(s) + HCl(aq) → CaCl₂(aq) + H₂(g)
Answer : The molarity of
in the solution is 1.5 M.
Explanation : Given,
Moles of
= 3.0 mol
Volume of solution = 2.00 L
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :

Now put all the given values in this formula, we get:

Therefore, the molarity of
in the solution is 1.5 M.
