How Do I Get Rid Of A Mole On My Face Without Going For A Surgery To Remove It?

I have a small flat mole near my lips. Is there any way for me to remove it without going to see the dermatologist to have it surgically removed? Tried cutting it out with a razor blade but the mole just seems to reappear again. Is there any way to get rid of this annoying thing?

What Are Some Similarities And Differences Between 1 Mole Of Water Molecules And 1 Mole Of Copper Atoms?

I know what is similar is that it is 6.2times10^23 of the units and that it is different in that 1 is copper and 1 is water and one is atoms and 1 is molecules, so the copper makes up a certain number of molecules that are less than a mole while the water is a mole in itself. Is there anything else you can think of?
