How many liters of a 20% acid solution should be added to 10 liters of a 30% acid solution to obtain a 25% acid solution?
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "acid + acid = acid
\n" ); document.write( "0.20x + 0.30*10 = 0.25(x+10)
\n" ); document.write( "------
\n" ); document.write( "Multiply thru by 100 to get::
\n" ); document.write( "20x + 30*10 = 25x + 25*10
\n" ); document.write( "5x = 5*10
\n" ); document.write( "x = 10 liters (amt of 20% solution needed)
