Algebra.Com's Answer #275854 by lwsshak3(11628)![]() ![]() ![]() You can put this solution on YOUR website! let x = the amount (ml) of 45% mixture should be mixed with the 80% solution \n" ); document.write( "then 60-x = the amount (ml) of 80% mixture should be mixed with the 45% solution \n" ); document.write( "mixing these two amounts together will give 60 ml of a 60% solution.\r \n" ); document.write( "\n" ); document.write( ",45x+.8(60-x) =.6(60) \n" ); document.write( ".45x +48-.8x =36 \n" ); document.write( ".35x = 12x \n" ); document.write( "x =12/.35 =34.29 ml \n" ); document.write( "60-x =25.71 ml\r \n" ); document.write( "\n" ); document.write( "ans: 34.29 ml of the 45% mixture should be mixed with 25.71 ml of the 80% mixture to get 60 ml of a 60% solution of hydrochloric acid \n" ); document.write( " |
