Final answer:
The concentration of the NaOH solution with 0.05 moles in 150 cm³ is 0.333 M. This is calculated by converting 150 cm³ to liters and then using the formula: concentration = moles of solute / volume of solution in liters.
Step-by-step explanation:
The concentration of a solution is calculated using the formula: concentration (M) = moles of solute / volume of solution in liters. To determine the concentration of the NaOH solution containing 0.05 moles of NaOH in 150 cm³, we need to convert the volume to liters: 150 cm³ is equivalent to 0.150 liters (since 1 dm³ equals 1 liter and 1000 cm³ equals 1 dm³).
Using the formula C = n/V, where C is the concentration in moles per liter (mol · dm³), n is the number of moles of solute, and V is the volume of solution in liters, the concentration C is calculated as follows:
- Convert the volume of solution from cm³ to liters: 150 cm³ = 0.150 L.
- Calculate concentration: C = 0.05 moles / 0.150 L = 0.333 mol · dm³ (or M).
Therefore, the concentration of the NaOH solution is 0.333 M.
