To calculate the concentration of the solution in units of molarity, we need to determine the number of moles of glucose dissolved in the solution and then divide it by the volume of the solution.<br /><br />Given information:<br />- Volume of the solution: 0 L<br />- Mass of glucose: 36.0 g<br /><br />Step 1: Calculate the molar mass of glucose (C6H12O6).<br />Molar mass of glucose = (6 × 12.01) + (12 × 1.01) + (6 × 16.00) = 180.16 g/mol<br /><br />Step 2: Calculate the number of moles of glucose.<br />Number of moles of glucose = Mass of glucose / Molar mass of glucose<br />Number of moles of glucose = 36.0 g / 180.16 g/mol = 0.2 mol<br /><br />Step 3: Calculate the concentration of the solution in units of molarity.<br />Concentration (M) = Number of moles of solute / Volume of solution (in liters)<br />Concentration (M) = 0.2 mol / 2.0 L = 0.1 M<br /><br />Therefore, the concentration of the solution in units of molarity is 0.1 M.
