Question

the mass by mass percentage of solute 'X' in the solution of mass 250g is 6.25%. what is the value solute 'X' in Kg?​

Answer 1

Answer:

Mass by the mass percentage of solute$'X'$ in the solution of the mass( $250g$ )  is $6.25$%, the value $'X'$ is $0.0156kg$

Explanation:

Given that,

Mass of solute in the solution = $Xg$

Mass of the solution = $250g$

Mass of the solution = mass of solute + mass of solvent

The mass percentage is defined as the ratio of the mass of solute to the mass of solution in percentage.

Mass percentage = $\frac{mass of solute}{mass of solution}$ ×$100$

                         $6.25$= $\frac{X}{250}$ ×$100$

                           $X=\frac{6.25}{100}$×$250$

                                =  $15.625g$ ≈ $0.0156kg$
