Question
Calculate the concentration of the 0.0400 mol/dm³ NaOH(aq) in g/dm³.
g/dm³ [2]
concentration =
Solution
To calculate the concentration of the NaOH(aq) solution in g/dm³, you need to know the molar mass of NaOH. The molar mass of NaOH is approximately 40 g/mol.
Step 1: Identify the given values. The molar concentration of NaOH = 0.0400 mol/dm³
Step 2: Use the formula for calculating the mass concentration. Mass concentration = Molar concentration x Molar mass
Step 3: Substitute the given values into the formula. Mass concentration = 0.0400 mol/dm³ x 40 g/mol
Step 4: Calculate the mass concentration. Mass concentration = 1.6 g/dm³
So, the concentration of the 0.0400 mol/dm³ NaOH(aq) solution is 1.6 g/dm³.
