Answer:
10,57%
Explanation:
The percent by weight can be expressed as:
[tex]percent by weight=\frac{Solute(g)}{solution(g)} x 100%\\[/tex] %
Now we have that the mass of the solution is
Mass of solution = mass of solute + mass of solvent
Mass of solution = 6,5g + 55,0g
Mass of Solution = 61,5g
∴ [tex]percentbyweight=\frac{6,5g}{61,5g} x100&=10,57[/tex]%
