Calculate the concentration of a solution which contains 2.5 g of salt dissolved in 50 g of water.
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
$concentration= \frac {mass\ of\ solute}{mass\ of\ solution}×100$
=2.552.5×100
=4.7%
Hence, the concentration is 4.7%
