from 2 stock solutions 18% and 42% you are to prepare 1.5 liters of a 34% solution. How many milligrams of each stock do you need?
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "active + active = active
\n" ); document.write( "0.18x + 0.42(1.5-x) = 0.34*1.5
\n" ); document.write( "----
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "18x + 42*1.5-42x = 34*1.5
\n" ); document.write( "-24x = -18
\n" ); document.write( "x = 3/4 liters (amt of 18% solution needed)
\n" ); document.write( "---
\n" ); document.write( "1.5-x = 3/4 liters (amt of 42% solution needed)
