Answer:
7.4%
Explanation:
MASS OF SOLUTE = 20g
VOLUME OF SOLVENT = 250ml
VOLUME OF SOLUTION= 20+250
= 270ml
CONCENTRATION(mass by volume percentage)=
=20/270 x 100
=0.74 x 10
= 7.4%

Answer:8%
Explanation:
Mass of solvent (acetic acid)= 20g
Mass of solute (water)= 250 ml
So,
Concentration of acetic acid solution
= Mass of solute/ Mass of solution×100
= 20/250×100
=2000/250
= 8%
Therefore, concentration of acetic acid solution is 8%.
