Hello!
A 250 mL sample of a 0,125 M solution of NaOH contains
1,25 g of NaOH
To calculate that, we use the definition of molar concentration (M=moles/L) and the solution volume in L to get the moles of NaOH in the solution. After that, we get the mass of NaOH from the molar mass. All these calculations are shown in the following conversion factor:
