Algebra.Com's Answer #582849 by macston(5194)![]() ![]() You can put this solution on YOUR website! 3.5% of 100 ounces is 3.5 ounces iodine. The question is how much alcohol to add to 3.5 ounces iodine to have a 1.5% solution: 3.5oz/0.015=233.3 ounces. The total solution will be 233.3 ounces and you already have 100 ounces, so you must add (233.3 ounces-100 ounces)=133.3 ounces of alcohol. \n" ); document.write( "-OR- \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Percentages must be in decimal form(i.e. 15%=0.15) \n" ); document.write( ". \n" ); document.write( " |
