You can put this solution on YOUR website!
If 1 percent solution is 10000 mg/L and 0.2 is 1/5
\n" ); document.write( "So 0.2 percent solution will be 2000 mg/L
\n" ); document.write( "1 kg = 1000000 mg so you have
\n" ); document.write( "0.2 percent solution is 0.002 kg/L
\n" ); document.write( "You need 90L, so you have 0.002*90 = 0.18
\n" ); document.write( "TA-DAH
\n" ); document.write( "Your answer is 0.18kg :D
\n" ); document.write( " \n" ); document.write( "
