You mostly divide the mass of the element for example the 1 mole of the compound in the compounds of molar mass and then you must multiply the result by 100 to get the percent or on the mass of a substance [tex]\sf{(m/m)}[/tex].

[tex] \large\textrm{ mass \red\% = } \rm{ \frac{mass}{total \: mass} \times \underline{100} \: \green \% }[/tex]

[Example]

  • [tex] \rm{(6 \cancel { \red{g}}/103 \cancel{ \blue{g}}) \times \underline{100} = \sf{5.66} \: \rm{ \green\%}}[/tex]

or..

Percent by mass, is the amount of solute in a mass of solvent expressed as grams solute per 100 grams of solution.

[tex] \normalsize\textrm{ mass of \red{solute} / mass of \blue{solution} × \underline{100} \green\%}\:\:[/tex]

[tex] \\ [/tex]

Hope Its Helps!

Aral Mabuti!
