Given : A solution contains 30 g of common salt in 140 g of water.
To find : Calculate the concentration of solution?
Applying formula :
1) Mass of solution = Mass of solute + Mass of solvent.
2) Mass percentage = Mass of solute/Mass of solution × 100.
Calculations :
→ Mass of solution = 30 + 140
→ Mass of solution = 170
→ Mass percentage = 30/170 × 100
→ Mass percentage = 0.176 × 100
→ Mass percentage = 17.6%
Therefore, 17.6% is the mass percentage of the solution.
