Question

0.5 gram of salt is dissolved in 25 gram of what did the percentage amount of the salt in the solution

Answer 1

Mass of solute = 0.5 g

Mass of solvent = 25 g

∴ Mass of solution = 25 g + 0.5 g = 25.5 g

We know,

Mass by mass % of concentration = (Mass of solute)/(Mass of solution) × 100%

⇒% of concentration = (0.5 g)/(25.5 g) × 100%

= 1/51 × 100% = 1.96%
