A Chemist has 100g of 25% acid solution. How much of these solution he needs to drain and replaced with 70% acid solution to obtain 100g of 60% acid solution
\n" ); document.write( "let x=amt of 25% solution to drain and replace with 70% solution
\n" ); document.write( "25%
\n" ); document.write( "25%(100-x)+70%x=60%100
\n" ); document.write( "25-.25x+.70x=60
\n" ); document.write( ".50x=35
\n" ); document.write( "x=70
\n" ); document.write( " How much of these solution he needs to drain and replaced with 70% acid solution to obtain 100g of 60% acid solution? 70 mg \n" ); document.write( "
