Molarity = moles / Volume in liters

M = 0.45 / 3.0

M = 0.15 mol/L 

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]
