Q1.
The student repeated the investigation.
The student used solutions that had different concentrations from the first investigation.
The student found that 15.5 cm3 of 0.500 mol/dm3 dilute sulfuric acid completely reacted with 25.0 cm3 of potassium hydroxide solution.
The equation for the reaction is:
Calculate the concentration of the potassium hydroxide solution in mol/dm3 and in g/dm3 Relative atomic masses (Ar): H = 1 O = 16 K = 39

Concentration in mol/dm3 = _____________________ mol/dm3
Concentration in g/dm3 = ______________________ g/dm3 (6)
