How many millilitres of water much be added to 100mL of a 50% solution of sulphuric acid to make a 10% solution?
\n" ); document.write( ":
\n" ); document.write( "let x = amt of water required to accomplish this
\n" ); document.write( ":
\n" ); document.write( "Write an amt of acid equation
\n" ); document.write( ".50(100) = .10(100+x)
\n" ); document.write( ":
\n" ); document.write( "50 = 10 + .1x
\n" ); document.write( ":
\n" ); document.write( "50 - 10 = .1x
\n" ); document.write( ":
\n" ); document.write( "x = $\"40%2F.1\"$
\n" ); document.write( "x = 400 ml of water required
\n" ); document.write( ":
