To prepare the given laboratory solutions, follow these steps: ### i) 250 ml of 0.2 M NaOH The molarity equation is: \[ M = \frac{\text{mass of solute (g)}}{\text{molar mass of solute (g/mol)} \times \text{volume of solution (L)}} \] 1. Calculate the required mass of NaOH - Molar mass of NaOH = 40 g/mol - Desired molarity = 0.2 M - Desired volume = 250 ml = 0.250 L \[ \text{Mass} = 0.2 \times 40 \times 0.250 ___ _____ _________ _____ __________ ____ _______ _____.
