Answer:
[tex]\displaystyle \text{ 3 M}[/tex]
Explanation:
Molarity is given by the ratio of the amount of moles of the solute over the total volume of the solution. That is:
[tex]\displaystyle \text{M} = \frac{\text{ mols solute}}{\text{ L soln.}}[/tex]
Substitute:
[tex]\displaystyle \begin{aligned} \text{M} & = \frac{(1.5\text{ mol CaCO$_3$} ) } { (0.5\text{ L soln.} )} \\ \\ & = 3\text{ M}\end{aligned}[/tex]
In conclusion, the solution is 3 molar.
