Hi

 preparing a 5% solution of baking soda in 500mls(500gm) of water 

 Let x represent the number of grams of baking soda to add    

   x = .05(x+500)

     .95x = 25

        x = 25/.95 

        x = 26.3158

      

Will need to add 26.3158gm of baking soda to the 500ml of water

 To prepare a 5% solution of baking soda in 500mls of water how much baking soda do I need and how would I mathmatically figure this?


Baking soda is measured by weight, so we must consider the solution is by
weight, not by volume.  1 milliliter of water weighs 1 gram.  So let x be the
number of grams of baking soda to add.  Then the concoction would weigh 100+x
grams.

So we have the equation:















 grams of baking soda.
