Dowex 50 is a wellknown ion exchanger.
In dowex 2 the active part is -N(CH3)2(C2H4OH)(+) (all three groups linked with nitrogen atom, of course - I don't know if this formula is clear) and dowex 50 is simply -SO3(-)
The answer depends on the units used for 50*50. It should be obvious to anybody that the area of a 50 ft * 50 ft room will be quite different to that of a 50 hectometre * 50 hectometre room, for example.
No 50 mm = 5 cm only
50 meters = 54.6806649 yards

"Dowex 50" is a type of ion-exchange resin, called a strongly acidic cation exchanger, used for ion-exchange chromatography. It is useful for swapping a metal cation for a proton (eg. Na+ for H+) or one metal cation for another (eg. K+ for Na+). This can be an important way for purifying amino acids, carboxylate salts or removing unwanted metal ions from water solutions.
