should get around 3 chains to a cassette! if cleaned and lubed properly i used a fine silicone spray on mine every time went out for a reasonable ride it was for sewing machines hell if got on carpet as slippry!!!
as been said it's out of adjustment on front mech.
If on 9 speed KMC or scram chains with tooless link so can flip apart and clean used to use Comma Hyper clean on all mine better than gunk it leaves a non rusting film on things drop chain into a tub with it in swish it around drain chain off then rinse with boiling water that way dries inside links the oil it easy if hanging up wipe down with rag/cloth then stick back on but what you don't want is lots of oil or grease on chain as turns into grinding paste!
If oil on bike and doing dab on each sides of links with likes of dri lube start at tool less link for a refference point then turn crank backwards once done piece of rag around low half of chain then backwind to wipe of excess can do same if using a spray.
Cassette take wheel out and paint some gunk on with cassette facing down when cleaning off. i used to take mine off once in a while to clean so reset it on splines
Kept clean and oiled will last far better Shimano chains are a law onto themselves! rarely ever used when was racing etc preferred Sedis/Sram/KMC and a few others like Rolhoff
