You can put this solution on YOUR website!
The initial volume of minoxidil = (0.04)(20 ml) = 0.8 ml
\n" ); document.write( "Let x = the number of ml of water needed
\n" ); document.write( "A 2% solution will have 0.8 ml of minoxidil and x + 20 ml of solution:
\n" ); document.write( "0.8/(x+20) = 0.02
\n" ); document.write( "x+20 = 0.8/0.02
\n" ); document.write( "Solving for x gives x = 40 - 20 = 20
\n" ); document.write( "So 20 ml of water should be used \n" ); document.write( "

\n" );
