In Norway the standard hours are 8-16 (8am/4pm) which includes half an hour lunch. I believe that in Sweden it's 8-17 (8 hours work, 1 hour lunch).
It's also normal to have three months of notice (and it's not optional for the worker). It's not uncommon that they'll let you leave with a shorter notice if you ask for it, unless they really need you during that time (for e.g. training new staff).
