Answer:
5.8 %
Explanation:
% by mass = (mass of solute/mass of solution) × 100 %
Data:
Mass of NaBr = 9.6 g
Mass of solution = 165 g
Calculation:
% by mass = (9.6 g/165 g) × 100 % = 5.8 %
Answer:
The concentration of sodium bromide solution as a percent by mass is 5.82%.
Explanation:
Percent by Mass (w/w %) :
The percentage mass or fraction of mass of the of solute present in total mass of the solution.
[tex]w/w\%=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100[/tex]
Mass of solute that is sodium bromide = 9.6 g
Mass of the solution prepared = 165 g
The concentration of solution as a percent by mass:
[tex]\frac{9.6 g}{165 g}\times 100=5.82\%[/tex]
