0.5 gm of salt dissolved in 25gm of water calculate the percentage amount of salt in the solution |
| Answer» Given, Mass of salt present = 0.5 gMass of water present in solution = 25 gMass of solution = Mass of salt + Mass of solvent =0.5 + 25= 25.5 g{tex}\\therefore{/tex} Percentage amount of the salt in solution={tex}\\frac{Mass\\;of\\;salt}{Mass\\;of\\;solution}\\times100{/tex}=\xa0{tex}\\frac{0.5}{25.5} \\times 100=1.96 \\%{/tex} | |
