# Kc Question watch

1. Wonder as to why must times it by 5? Never came across this before and I am guessing it's cause of the 500K.

Also aren't you meant to divide the Equilibrium amount by say 0.2dm3 or 200cm3 or something? Or is the 200 vol info irrelevant for this part of the Q?
2. It is in a 200 cm3 container.

You want concentration in mol dm^-3. You already have 200cm^3 so you need 1000cm^3 (1dm^3) so you times it by 5.

In reality dividing it by 0.2 would have the exact same effect
