what are skin tags and how do they form> what causes them?

I need to know if there is a product I can use over the counter that can get rid of moles I have a bunch I would like toget rid of, but the only one the doctor wil remove is the only one changing colors I have about 2 dozen all over my body. Most of the moles are on the same excat arm that the changing mole is on. I am scared. I was wonderingif I can get rid of them at home safely with no concerns of Malignant Melanoma. Keep in mind I am going to make her get rid of as many as I can, but could I do something at home to get rid of the rest? Thank You!

A 2.500 g sample of a mixture of sodium carbonate and sodium chloride is dissolved in 25.00 mL of 0.798 M HCl. Some acid remains after the treatment of the sample.

If 28.8 mL of 0.108 M NaOH were required to titrate the excess hydrochloric acid, how many moles of sodium carbonate were present in the original sample?
