Calculate the concentration of a solution which contains 2.5 g of salt dissolved in 50 g of water.

`"concentration" = "mass of solute"/"mass of solute+ mass of solvent"xx100 `

Given, Mass of salt is 2.5 gm and mass of water is 50 gm.

So, total mass of the solution = 50 gm + 2.5 gm  = 52.5 gm

Hence, concentration `=2.5/52.5 xx 100 = 4.7%`

What is the concentration of a solution which contains 16 g of urea in 120 g of solution ?

Given, Mass of urea = 16 gm
Mass of solution = 120 gm  

`"concentration" = "mass of solute"/"mass of solute + mass of solvent"xx100`

`=16/20xx100`

= 13.333%

Therefore, the concentration is 13.333%.
