Answer :
The concentration of the solution prepared from 50. g nacl and 2.5 l of water will be 2 %.
The proportion of the mass of the solute contained in a solution to the volume of the solution in its entirety is known as the mass/volume percent. The given proportion should be multiplied by 100 because this sort of concentration has been represented as a percentage.
The calculation if concentration is shown as:
It can be calculated by mass percent formula:
% (m/v) NaCl = Mass of NaCl / Total mass × 100 %
% (m/v) NaCl = 50 gram / 2500 × 100 %
% (m/v) NaCl = 2 %.
Therefore, the concentration of the solution prepared from 50. g nacl and 2.5 l of water will be 2 %.
