Answer 1

Answer:

0.422 mol/L.

Explanation:

• Molarity (M) is the no. of moles of solute dissolved in a 1.0 L of the solution.

M = (no. of moles of glucose)/(volume of the solution (L))

M = (mass/molar mass)of glucose / (volume of the solution (L)).

∴ M = (mass/molar mass)of glucose / (volume of the solution (L)) = (289 g/342.2965 g/mol)/(2.0 L) = 0.422 mol/L.
