Recall that molarity (M) is defined as the number of moles of solute divided by the volume of the solution in liters. The formula is: \(M = \frac{\text{moles of solute}}{\text{volume of solution in liters}}\).
Identify the given values: moles of solute = 6 moles, volume of solution = 2 liters.
Substitute the given values into the molarity formula: \(M = \frac{6}{2}\).
Perform the division to find the molarity (do not calculate the final number here, just set up the expression).
Interpret the result as the concentration of the solution in moles per liter (M).
