0.11 M is the molarity of solution containing 1.2 grams of solute in 450 mL of solution.
Molarity
Molarity (M) is defined as the number of moles of solute dissolved in 1L of solution. Molarity is also known as Molar concentration. The S.I Unit of Molarity is molar (M) or mol/L.
How to find molarity of a solution ?
Molarity (M) = [tex]\frac{\text{Mass of solute}}{\text{Molar mass of solute} \times \text{Volume in liter}}[/tex]
From the above definition it is clear that the volume of solution is in liter. In question the volume of solution is given in ml.
So, convert 450 ml into l.
450 ml = [tex]\frac{450}{1000}[/tex] = 0.45 l
Now, put the values in above formula, we get that
Molarity (M) = [tex]\frac{1.2}{24 \times 0.45}[/tex]
= [tex]\frac{1.2}{10.8}[/tex]
= 0.11 M
Thus, 0.11 M is the molarity of solution containing 1.2 grams of solute in 450 mL of solution.
