Question

a solutions contain 20 g of acetic acid and 250 ml of water .what is the concentration id acetic aci
d in solution.

Answer 1

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 2

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%.
