Algebra.Com's Answer #510712 by josgarithmetic(39618)![]() ![]() ![]() You can put this solution on YOUR website! The concentration of alcohol in the 100 ml. alcohol solution is still unknown. You do not then have a way to find how much water to add to make 20% alcohol. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Assuming percents are vol/vol, and you have 100 ml. of some c percent alcohol, and you want to add 40 ml. of water; AND also some v amount of 100% alcohol to make 20% solution, ...\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Amount of pure alcohol = \n" ); document.write( "Amount of solution result = \n" ); document.write( "Equation for adjustments to be 20% alcohol: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Simplified: \n" ); document.write( "further simplifiable based on the convenient numbers, \n" ); document.write( " \n" ); document.write( "OR \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Recheck your problem description for better/more precise problem description or for any missing information omitted from your help request. \n" ); document.write( " |
