Question

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

Answer 1

Answer:

given the mass of solute (salt) = 2.5 g

and mass of solvent (water) = 50g

as we know that mass of solution = mass of solute + mass of solvent

= 2.5 + 50

= 52.5g

concentration of the solution = (mass of solute/mass of solution) × 100

= (2.5/52.5) × 100

= 250/52.5

= 4.76% (approximately)

Answer 2

Answer:-

0.0457%

Explanation:-

Concentration of solution =  Amount of solution  / Amount of salt×100

                                          =  5+100  / 5×100

​                                           =  105  / 5×10

                                          =4.76%
