Mass of NaOH must you dissolve in enough water to make 5.00 × 10² mL solution in order to create a 0.267 M solution is 5.32 g.
Given that :
molarity = 0.267 M
volume = 5.00 × 10² mL = 0.5 L
molarity expression is given as :
molarity = moles / volumes in L
moles = molarity × volume
moles = 0.267 × 0.5
moles = 0.133 mol
mass of NaOH = moles × molar mass
mass of NaOH = 0.133 mol × 40 g/mol
mass of NaOH = 5.32 g
Thus, Mass of NaOH must you dissolve in enough water to make 5.00 × 10² mL solution in order to create a 0.267 M solution is 5.32 g.
