Mass of salt needed : 48 g
Further explanation
The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight/volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
A 600g 8% solution
m solution = 600 g
% mass = 8%
[tex]\tt \%mass=\dfrac{mass~solute}{mass~solution}\times 100\%\\\\8\%=\dfrac{mass~of~salt}{600}\times 100\%\\\\mass~of~salt=\dfrac{8\times 600}{100}=48~g[/tex]
