검증된 단계별 안내1
Identify the known quantities: the amount of solute (NaOH) is 1.90 mol, and the concentration (molarity, M) is 0.555 M.
Recall the definition of molarity: \(M = \frac{\text{moles of solute}}{\text{volume of solution in liters}}\).
Rearrange the molarity formula to solve for volume: \(\text{Volume} = \frac{\text{moles of solute}}{M}\).
Substitute the known values into the equation: \(\text{Volume} = \frac{1.90\ \text{mol}}{0.555\ \text{mol/L}}\).
Calculate the volume using the above expression to find the volume of the NaOH solution in liters.
