Answer: 0.15 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
[tex]Molarity=\frac{moles}{\text {Volume in L}}[/tex]
Moles are calculated by dividing the given mass by molecular mass of that substance.
[tex]Molarity=\frac{0.45moles}{\text {3.0 L}}[/tex]
[tex]Molarity=0.15M[/tex]
