Verified answer

Explanation:

[tex]\large{\sf \underline{\underline{ Given:-}}}[/tex]

[tex]\sf Mass \: of \: common \: salt(Solute) = x \: g[/tex]

[tex]\sf Mass \: of \: Water (Solvent)= 48 \: g[/tex]

[tex]\sf Concentration_{solution}=12.4 \%[/tex]

[tex]\large{\sf \underline{\underline{ To \: find:-}}}[/tex]

• [tex] \sf Value \: of \: x [/tex]

[tex]\large{\sf \underline{\underline{Solution:-}}}[/tex]

[tex]\sf \bf We \: know \: that,[/tex]

[tex] \pmb{\underline{\boxed{\sf Concentration_{solution}=\dfrac{Mass \: of \: solute}{Mass \: of \: solvent}×100}}}[/tex]

[tex]\sf 12.4 \%=\dfrac{x}{48}×100[/tex]

[tex]\sf : \implies x = \dfrac{12.4×48}{100}[/tex]

[tex]\sf : \implies x = \dfrac{595.2}{100}[/tex]

[tex]\sf : \implies \underline{\boxed{\sf \bf x = 5.95 \: g}}[/tex]
