FREE Expert Solution

We are asked to which solution has the same number of moles of NaOH as 50.0 mL of 0.100 M solution of NaOH


Recall dilution equation: 

mol = MV


Calculate mol for 50.0 mL of 0.100 M solution of NaOH

mol NaOH= MVmol NaOH=(0.10 mol L)(50 mL)×10-3  L1 mL  = 5×10-3 mol


Calculate mole for each option:
