Molarity of 0.50 mol sugar in 270 mL of solution.

1.85 M

Explanation:

We are given;

Number of moles as 0.50 mol Volume of the solution is 270 ml

But, 1000 mL = 1 L

Thus, volume of the solution is 0.27 L

We are required to calculate the molarity of the solution;

Molarity refers to the concentration of a solution in moles per liter. It is calculated by dividing number of moles with the volume.

Molarity = Moles : Volume

In this case;

Molarity = 0.50 moles : 0.27 L

= 1.85 Mol/L or 1.85 M

Therefore, molarity of the solution is 1.85 M
