Question

what is the concentration of a solution which contains 2.5gram of salt dissolved in 50 gram of water​

Answer 1

Answer:

4.761 %

Explanation:

Mass of solute (salt): 2.5 g

Mass of solvent (water): 50 g

We know,

Mass of solute = Mass of solute + Mass of solvent

=2.5 g + 50 g

=52.5 g

Concentration of the solution:

= Mass of solute × 100/ Mass of solution

= 25 × 100/525

=4.761 %
