A3.0% (m/v) potassium chloride solution has a volume of 25.0 ml. how many moles of potassium chloride are in the sample? i would answer this. but my teacher skimmed through this section of the text. and he won’t me with it. i just know that m/v is g/ml and mls should cancel out right? and moles come from mole/l. i am not sure what to do though.

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.

hope this and can i get bainliest my dude : d

answer the questions honestly.
