Answer:
0.422 mol/L.
Explanation:
- <em>Molarity (M)</em><em> is the no. of moles of solute dissolved in a 1.0 L of the solution.</em>
<em />
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.
