Sagot :
I'm going to solve it using the GRESA form.
G : m solute = 20 grams; solvent = 250 grams
R : percent by mass
E : % bm = [tex] \frac{m solute}{m solution} [/tex] x 100; solution = solute + solvent
S : % bm = [tex] \frac{m solute}{m solution} [/tex] x 100
= [tex] \frac{20}{250} x 100[/tex]
= 0.08 x 100
= 8
A : 8%

Asked: What is the percentage by mass?
Percentage by Mass of Solute (salt)
= [tex] \frac{mass of solute}{mass of solution} [/tex]
= [tex] \frac{20g}{20g + 250g} [/tex]
= [tex] \frac{20g}{270g} [/tex]
= 7.40% (rounded off to the nearest hundredths)
Percentage by Mass of Solvent (water)
= [tex] \frac{mass of solvent}{mass of solution} [/tex]
= [tex] \frac{250g}{250g + 20g} [/tex]
= [tex] \frac{250g}{270g} [/tex]
= 92. 60% (rounded off to the nearest hundredths)
Percentage by Mass of Solute (salt)
= [tex] \frac{mass of solute}{mass of solution} [/tex]
= [tex] \frac{20g}{20g + 250g} [/tex]
= [tex] \frac{20g}{270g} [/tex]
= 7.40% (rounded off to the nearest hundredths)
Percentage by Mass of Solvent (water)
= [tex] \frac{mass of solvent}{mass of solution} [/tex]
= [tex] \frac{250g}{250g + 20g} [/tex]
= [tex] \frac{250g}{270g} [/tex]
= 92. 60% (rounded off to the nearest hundredths)
