You can put this solution on YOUR website!
There is 500g of a 10% salt solution.
\n" ); document.write( " If water is added to dilute this saline solution to 4% how many grams of water were added.
\n" ); document.write( ":
\n" ); document.write( "let a = amt added to accomplish this
\n" ); document.write( ":
\n" ); document.write( "the amt of salt does not change, therefore
\n" ); document.write( " .04(a + 500) = .10(500)
\n" ); document.write( " .04a + 20 = 50
\n" ); document.write( ".04a = 50 - 20
\n" ); document.write( ".04a = 30
\n" ); document.write( "a = 30/.04
\n" ); document.write( "a = 750 grams of water needs to added
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check by finding the amt of salt in each solution, should be equal
\n" ); document.write( ".04(750+500) = 50
\n" ); document.write( ".10(500) = 50
\n" ); document.write( "
\n" );
