\r\n" );
document.write( "Let V be the volume of the 75% acid solution to be mixed.\r\n" );
document.write( "Then the volume of the 30% solution must be 1080 mL.\r\n" );
document.write( "\r\n" );
document.write( "Your governing equation is the concentration equation\r\n" );
document.write( "\r\n" );
document.write( " = 0.5.\r\n" );
document.write( "\r\n" );
document.write( "Simplify and solve it:\r\n" );
document.write( "\r\n" );
document.write( "0.75V + 324 - 0.3V = 0.5*1080,\r\n" );
document.write( "\r\n" );
document.write( "0.45V = 540 - 324  --->  0.45V = 216  --->  V =  = 480 mL.\r\n" );
document.write( "\r\n" );
document.write( "Answer.  480 mL of the 75% solution must be mixed with 1080-480 = 600 mL of the 50% solution.\r\n" );
